Product details
Overview
MAX901AESE-T from Maxim Integrated is a high-speed, low-power dual voltage comparator with differential analog inputs and TTL-compatible outputs, 8ns typical propagation delay at 5mV overdrive, ±5V or +5V single-supply operation, and input common-mode range extending to the negative rail - used in high-speed A/D converter front-ends and line receiver circuits.
For engineers reviewing the MAX901AESE-T datasheet, MAX901AESE-T pinout, MAX901AESE-T application, or MAX901AESE-T equivalent, this page delivers verified electrical specs, package mapping, latch-free dual-comparator functionality, thermal performance across -40°C to +85°C, and validated alternatives for legacy design continuity.
Technical Context
The MAX901AESE-T implements two independent high-gain, wide-bandwidth comparators with separate analog (VCC/VEE) and digital (VDD) supply domains, enabling noise-isolated mixed-signal operation. Its input stage supports ground-sensing on single +5V supplies and tolerates common-mode voltages from VEE − 0.1V to VCC − 2.25V.
No internal latches are present - unlike MAX900/MAX902/MAX903 - eliminating latch timing constraints (ts, th, tpw(D)) and simplifying control logic. Output stages drive TTL loads directly with VOH ≥ 2.4V (ISRC = 1mA) and VOL ≤ 0.4V (ISINK = 8mA), supporting fan-out of four low-power Schottky TTL devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 8ns typical (tpd+, tpd−) at 5mV overdrive, CL = 15pF - enables sampling at >100MHz effective rates in A/D interfaces. |
| Input Offset Voltage | 1mV min / 3mV max over full temperature range - ensures sub-mV threshold accuracy in precision level detection. |
| Supply Range | Analog: ±5V or +5V to +10V (VEE grounded); Digital: +5V only - supports flexible biasing in mixed-signal systems. |
| Power Dissipation | 70mW per comparator at +5V (ICC = 10–25mA, IEE = 7–20mA, IDD = 4–10mA) - balances speed and thermal load in dense layouts. |
| Input Common-Mode Range | VEE − 0.1V to VCC − 2.25V - allows direct sensing of signals referenced to ground or negative rails without level-shifting. |
| Output Drive Capability | VOH ≥ 2.4V @ 1mA source; VOL ≤ 0.4V @ 8mA sink - meets TTL logic thresholds with margin for bus loading. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and automotive under-hood environments requiring extended thermal stability. |
Pinout & Package
MAX901AESE-T is housed in a 16-pin narrow SOIC (SO) package (body width 3.9mm), RoHS-compliant, with standard JEDEC MS-012AC footprint and 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | IN− (A, B) | Negative input terminals for comparator channels A and B - differential pair inputs with rail-to-rail common-mode support. |
| 2, 9 | IN+ (A, B) | Positive input terminals for comparator channels A and B - accept fast transient signals up to 100MHz without oscillation when layout-optimized. |
| 3 | GND | Digital and analog reference ground - must connect to low-inductance ground plane; separates signal return from power return paths. |
| 4, 11 | LATCH (A, B) | No-connect (N.C.) - MAX901 lacks internal latches; pins are unconnected and must be left floating or tied to GND/VDD per layout best practice. |
| 5, 12 | OUT (A, B) | TTL-compatible open-collector outputs with internal pull-ups - drive logic-level signals directly; no external pull-up required for TTL loads. |
| 6, 13 | N.C. | No internal connection - electrically isolated; may be left unconnected or used as thermal pad anchor if soldered to copper pour. |
| 7 | VEE | Negative analog supply and substrate tie - must be connected to −5V (split supply) or GND (single supply); critical for input range and noise immunity. |
| 10 | VDD | +5V digital supply - powers output stage only; decoupling capacitor (100nF ceramic) required within 5mm of pin. |
| 14 | VCC | Positive analog supply - accepts +5V to +10V; decoupling capacitor (100nF ceramic) required adjacent to pin for high-speed stability. |
Key Features
| Feature | Design Value |
|---|---|
| 8ns propagation delay | Enables real-time discrimination of <10ns input transitions in high-speed data acquisition and clock recovery paths. |
| Rail-to-rail input common-mode range | Supports direct interface to sensors, DACs, and ADC drivers operating at ground or negative references without external biasing. |
| Separate analog/digital supplies | Prevents digital switching noise from coupling into analog inputs via shared VDD/VCC paths - improves SNR in mixed-signal PCBs. |
| 18mW/comparator power consumption | Reduces thermal density in multi-channel comparator arrays while maintaining nanosecond response - suitable for compact industrial modules. |
| TTL-compatible outputs | Eliminates need for level translators when interfacing with FPGA I/O banks, microcontroller GPIOs, or legacy logic families. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|

Use Scenario: Front-end threshold comparison for flash or pipeline ADCs sampling at 50–100MSPS. IC Role / Device Role / Timing Role: Dual comparator providing synchronized decision points for parallel bit slicing with matched propagation delay (<2ns skew). Use Value: 8ns tpd ensures <10ps timing jitter contribution to aperture uncertainty, preserving ENOB in 8–10-bit converters. |
Use Scenario: Differential signal recovery from twisted-pair or coaxial transmission lines in industrial fieldbus nodes. IC Role / Device Role / Timing Role: High-speed comparator converting small-swing NRZ signals into clean TTL logic levels with minimal intersymbol interference. Use Value: Input common-mode range down to VEE − 0.1V allows direct termination at receiver ground, avoiding DC bias networks and saving board space. |
| Threshold Detectors | PWM Circuits |
|
Use Scenario: Real-time overvoltage/undervoltage monitoring in DC-DC converter feedback loops or battery management systems. IC Role / Device Role / Timing Role: Dual-channel comparator comparing sensed rail voltage against precision reference to trigger fault flags or enable/disable control logic. Use Value: 1mV min input offset ensures detection of <10mV deviations from setpoint - critical for tight-tolerance Li-ion cell balancing. |
Use Scenario: Edge-triggered PWM generation in motor gate drivers or LED dimming controllers using triangle-wave comparators. IC Role / Device Role / Timing Role: Comparator comparing ramp waveform against control voltage to produce duty-cycle-modulated square wave output. Use Value: Matched tpd+ and tpd− (≤1ns difference) guarantees symmetrical rise/fall timing, minimizing dead-time distortion in H-bridge gate signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202ESE+ | Pin-for-pin compatible; 8ns tpd, but 9mW/comparator (half power); includes latch inputs (not used in MAX901). | Requires unused latch pins to be tied high; lower power enables higher channel density in thermally constrained designs. | Select MAX9202ESE+ when upgrading legacy MAX901 designs for reduced thermal load and long-term supply continuity. |
| LM319M/NOPB | Slower (80ns tpd), wider supply range (±15V), no latch, SOIC-14 package - not pin-compatible; requires PCB redesign. | Suitable for general-purpose industrial comparators where speed is secondary to voltage range and cost. | Choose LM319M/NOPB only for non-speed-critical replacements where ±15V operation or TI's long-term availability outweighs layout change cost. |
Compared with MAX901AESE-T, MAX9202ESE+ offers identical speed and pinout with halved power dissipation - ideal for drop-in thermal upgrades - while LM319M/NOPB trades speed for broader supply flexibility and vendor diversification at the cost of board rework.

FAQ
What is the operating temperature range for MAX901AESE-T?
The MAX901AESE-T is rated for operation from -40°C to +85°C, meeting industrial-grade thermal requirements. This range is confirmed in the "Ordering Information" table and validated across all electrical specifications including input offset voltage (1–3mV), propagation delay (10–15ns), and supply current (ICC = 10–25mA) at temperature extremes.
Does MAX901AESE-T include internal latch circuitry?
No, MAX901AESE-T does not include internal latch circuitry - unlike MAX900, MAX902, and MAX903. Pins 4 and 11 are labeled LATCH (A, B) in the pinout but are explicitly designated as N.C. (no connection) in the datasheet, and all latch-related timing parameters (ts, th, tpw(D)) are marked "Not applicable to MAX901."
What are the valid supply configurations for MAX901AESE-T?
MAX901AESE-T supports three configurations: (1) split ±5V analog supplies (VCC = +5V, VEE = −5V) with VDD = +5V; (2) single +5V analog supply (VCC = +5V, VEE = GND) with VDD = +5V; or (3) extended +5V to +10V analog supply (VEE = GND). VDD must always be +5V; analog supplies exceeding +10V or −5V violate absolute maximum ratings.
Can MAX901AESE-T operate from a single 3.3V supply?
No, MAX901AESE-T cannot operate reliably from a single 3.3V supply. The datasheet specifies minimum analog supply voltage as +5V (VCC ≥ +5V) and requires VDD = +5V. Output VOH drops below 2.4V and VOL rises above 0.4V outside +5V digital supply, violating TTL logic thresholds - confirmed in Electrical Characteristics tables.
Is MAX901AESE-T pin-compatible with other MAX900-series variants?
MAX901AESE-T uses a 16-pin narrow SOIC package, while MAX900 (20-pin), MAX902 (14-pin), and MAX903 (8-pin) use different footprints - it is not physically pin-compatible. However, its dual-comparator function, pin numbering, and signal assignments (IN+, IN−, OUT, VCC, VEE, VDD, GND) align with the MAX901-specific 16-pin SO layout shown in the "Pin Configurations" section.
