Product details
Overview
The MAX9201EUE+T from Maxim Integrated is a quad, high-speed, low-power voltage comparator with TTL-compatible outputs and separate analog/digital supply rails (VCC/VEE and VDD), delivering 7ns typical propagation delay at 5mV overdrive, ±5V or +5V to +10V analog supply range, and 9mW per comparator power consumption - ideal for high-speed A/D converter front-ends and line receivers.
For engineers reviewing the MAX9201EUE+T datasheet, MAX9201EUE+T pinout, MAX9201EUE+T application, or MAX9201EUE+T equivalent, this device supports ground-sensing single-supply operation, features four independent comparator channels in a 16-pin TSSOP package, and offers precise timing control without output latching - distinguishing it from the latch-equipped MAX9202/MAX9203 variants.
Technical Context
The MAX9201EUE+T implements a bipolar process-based quad comparator architecture with fully differential inputs per channel, common-mode input range extending to the negative rail (VEE), and internally pulled-up TTL outputs capable of driving four LS-TTL loads. It operates with independent analog (VCC–VEE) and digital (VDD) supplies, enabling noise isolation in mixed-signal systems.
Unlike the MAX9202/MAX9203, the MAX9201EUE+T omits latch inputs entirely - all four comparators operate transparently with no hold functionality. Its input offset voltage is 7.5mV max over temperature, and propagation delay matching between channels is specified at ≤2.5ns (ΔtPD), critical for synchronized sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7ns typical (5mV overdrive, CL = 15pF) - enables sub-10ns decision timing in high-speed data acquisition. |
| Power Consumption | 9mW per comparator at +5V supply - reduces thermal load in dense PCB layouts. |
| Analog Supply Range | +5V to +10V (VCC) with VEE grounded, or ±5V - supports both single- and split-supply signal conditioning. |
| Digital Supply | VDD = +4.75V to +5.25V only - mandates stable 5V logic rail, not adjustable. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V - allows ground-referenced sensing in single-supply configurations. |
| Output Drive | VOH = 3.0V min (1mA source), VOL = 0.4V max (8mA sink) - ensures robust TTL-level interfacing. |
| Input Offset Voltage | 7.5mV max (−40°C to +85°C) - defines minimum detectable differential signal without calibration. |
Pinout & Package
MAX9201EUE+T is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad, rated for −40°C to +85°C operation. The package provides compact footprint (5mm × 4.4mm), fine-pitch leads (0.65mm), and thermal performance suitable for industrial signal-chain modules.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN_− | Negative input terminals for comparators A, B, C, D - differential pair emitters in bipolar topology. |
| 2, 7, 10, 15 | IN_+ | Positive input terminals for comparators A, B, C, D - differential pair bases accepting rail-to-rail common-mode signals. |
| 3 | GND | Digital ground reference for VDD and TTL output stages - must be low-inductance connection to minimize switching noise coupling. |
| 4, 5, 12, 13 | OUT_ | TTL-compatible open-collector outputs with internal pullups - drive LS-TTL directly; no external pullup required. |
| 6 | VEE | Negative analog supply and substrate bias - tied to ground in single-supply mode; sets lower common-mode limit. |
| 11 | VDD | +5V digital supply for output stage and internal logic - independent of analog rails for noise isolation. |
| 14 | VCC | Positive analog supply (4.75V–10.5V) - powers input differential pairs and defines upper common-mode range. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel independence | All four comparators share supply rails but operate electrically isolated - enables parallel threshold detection without crosstalk. |
| Rail-to-rail input capability | Common-mode range includes VEE - permits direct interface to ground-referenced sensors or DAC outputs in single-supply systems. |
| 7ns propagation delay matching | ΔtPD ≤ 2.5ns across channels - ensures synchronized decision timing for multi-bit sampling or phase-aligned triggering. |
| Bipolar process precision | 348-transistor die optimized for speed/power tradeoff - delivers 7ns delay at just 9mW, outperforming CMOS comparators of similar speed. |
| No latch circuitry | Distinguishes MAX9201EUE+T from MAX9202/MAX9203 - eliminates setup/hold timing constraints and simplifies control logic in transparent comparator applications. |
Applications
| High-Speed A/D Converter Front-End | Line Receiver with Signal Restoration |
|---|---|
Use Scenario: Digitizing analog waveforms at >50MSPS using flash or pipeline ADC architectures requiring ultrafast, low-jitter threshold decisions. IC Role / Device Role / Timing Role: Quad comparator providing simultaneous 1-bit quantization slices for thermometer-coded input; each channel drives one ADC bit slice with matched delay. Use Value: 7ns propagation delay and ≤2.5ns inter-channel skew minimize aperture uncertainty and improve effective resolution in high-speed sampling. |
Use Scenario: Recovering degraded digital signals from long cables or noisy industrial buses where amplitude loss and jitter accumulate. IC Role / Device Role / Timing Role: Threshold detector restoring logic levels by comparing incoming signal against precise reference; TTL outputs re-drive clean edges. Use Value: Input common-mode range including ground enables direct interface to terminated lines; 7ns response restores timing integrity before clock recovery circuits. |
| PWM Timing Comparator Bank | Multi-Threshold Detector for Sensor Monitoring |
Use Scenario: Generating multiple PWM outputs with precisely aligned edges in motor control or lighting drivers using shared clock and ramp generators. IC Role / Device Role / Timing Role: Four independent comparators comparing a common sawtooth ramp against four distinct DC thresholds to generate phase-shifted PWMs. Use Value: Matched propagation delay ensures edge alignment within 2.5ns - critical for minimizing dead-time errors and harmonic distortion in multi-phase inverters. |
Use Scenario: Monitoring four analog sensor outputs (e.g., temperature, pressure, current, voltage) against independent safety or alarm thresholds in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Standalone threshold detector converting analog sensor voltages into TTL-level fault flags; no microcontroller intervention required. Use Value: Single +5V supply operation with ground-sensing inputs simplifies power design; 9mW total quiescent power enables always-on monitoring in energy-constrained nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202EUD+ | Includes dual latch inputs (LATCHA/LATCHB); otherwise identical pinout, speed, and supply specs. | Requires latch control signals; used when output state must be held asynchronously (e.g., data capture strobes). | Select MAX9202EUD+ only if latch functionality is required; MAX9201EUE+T avoids latch timing constraints and simplifies control logic. |
| LM339MTX/NOPB | Slower (1.3µs typ), higher power (600µA per comparator), no separate digital supply, no latch, SO-14 package. | Targeted at general-purpose, non-critical timing applications; lacks speed and supply flexibility for high-end signal chains. | Choose LM339MTX/NOPB for cost-sensitive, low-speed designs where 7ns timing is unnecessary and board space allows larger SO-14. |
Compared with MAX9202EUD+, the MAX9201EUE+T removes latch complexity for transparent operation; compared with LM339MTX/NOPB, it delivers 185× faster response and 1/67th power per channel - making it essential for time-critical, power-sensitive industrial and test equipment.

FAQ
What is the maximum operating temperature range for the MAX9201EUE+T?
MAX9201EUE+T is rated for continuous operation from −40°C to +85°C ambient temperature. This industrial-grade temperature range is validated across all electrical specifications in the datasheet, including propagation delay, input offset voltage, and supply current. The device uses a bipolar process and TSSOP packaging engineered for thermal stability across this full range, making MAX9201EUE+T suitable for deployment in harsh environments such as factory automation controllers and outdoor communications infrastructure.
Does the MAX9201EUE+T support single-supply operation?
Yes, MAX9201EUE+T supports true single-supply operation: VEE is connected to ground, VCC is set to +5V to +10V, and VDD is +5V. Its input common-mode range extends to VEE − 0.1V, enabling ground-referenced input signals without level-shifting. This configuration is explicitly validated in the datasheet's "Typical Power-Supply Alternatives" section (Figure 1b) and confirmed by the −0.1V lower bound in the VCM specification. MAX9201EUE+T thus functions reliably in systems powered solely from a +5V rail.
What are the supply voltage requirements for analog and digital rails on the MAX9201EUE+T?
MAX9201EUE+T requires three supply connections: VCC (analog positive, +4.75V to +10.5V), VEE (analog negative, typically ground or −5V), and VDD (digital positive, +4.75V to +5.25V only). VDD must be tightly regulated at 5V - it is not adjustable and does not track VCC. The analog rails can be configured as single-ended (+5V to +10V with VEE = GND) or split (±5V), while VDD remains fixed. This separation isolates digital switching noise from sensitive analog inputs, a key design feature of MAX9201EUE+T.
How many comparator channels does the MAX9201EUE+T contain, and are they electrically isolated?
MAX9201EUE+T contains four fully independent comparator channels (A, B, C, D), each with dedicated IN_+, IN_−, and OUT pins. Electrical isolation between channels is confirmed by the absence of shared input or output circuitry in the functional block diagram and pin description - each channel uses its own differential pair and output stage. Inter-channel propagation delay matching (ΔtPD ≤ 2.5ns) further confirms independent yet tightly correlated timing paths. No shared bias or reference networks are present, ensuring channel-to-channel crosstalk remains below measurement threshold in the datasheet.
Is the MAX9201EUE+T pin-compatible with the MAX9202 or MAX9203?
No, MAX9201EUE+T is not pin-compatible with MAX9202 or MAX9203. Although all three share the same 16-pin TSSOP footprint (MAX9201) or 14-pin TSSOP (MAX9202) or 8-pin SOT23 (MAX9203), their pin functions differ significantly: MAX9201EUE+T assigns pins 4, 5, 12, 13 to OUT_, whereas MAX9202 repurposes pins 4 and 11 as LATCH_ inputs. The MAX9201EUE+T has no latch inputs at all - a deliberate architectural distinction. Swapping packages or variants without board redesign will result in incorrect signal routing and functional failure.
