Product details
Overview
The MAX962ESA from Maxim Integrated is a dual ultra-high-speed comparator with internal hysteresis, optimized for single +3V or +5V operation. It features 4.5ns propagation delay (5mV overdrive), 5mA supply current per comparator, Beyond-the-Rails™ input range (–0.1V to VCC + 0.1V), and TTL/CMOS-compatible outputs. It is used in GPS receivers and high-speed sampling circuits where precise, low-latency threshold detection is required.
For engineers reviewing the MAX962ESA datasheet, MAX962ESA pinout, MAX962ESA application, or MAX962ESA equivalent, key selection considerations include propagation delay vs. overdrive, input common-mode range beyond rails, output drive capability (4mA to within 0.52V of GND/VCC), shutdown absence (unlike MAX961/MAX963), and SO-8 package compatibility with space-constrained industrial timing and signal conditioning designs.
Technical Context
The MAX962ESA implements a current-driven output stage enabling fast slew rates and rail-to-rail output swing without external pull-ups. Its internal 3.5mV hysteresis eliminates need for external feedback resistors and prevents oscillation near trip points in noisy or slow-moving input environments.
Unlike MAX961/MAX963, it lacks latch-enable and shutdown functionality - confirmed by selector guide and pin configuration tables. It contains two independent comparators sharing only VCC and GND, with no inter-channel logic coupling or shared control inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision latency in high-frequency sampling and clock recovery. |
| Supply Voltage Range | +2.7V to +5.5V - supports direct interface with modern low-voltage microcontrollers and FPGAs. |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - allows detection of signals below GND or above VCC (e.g., AC-coupled sensor outputs). |
| Output Drive Capability | Sinks or sources 4mA to within 0.52V of GND or VCC - drives standard TTL/CMOS loads without external buffers. |
| Supply Current per Comparator | 5mA typical at VCC = 5V - balances speed and power for battery-sensitive portable instrumentation. |
| Input-Referred Hysteresis | 3.5mV - provides noise immunity without requiring external resistor networks. |
| Input Offset Voltage | ±0.5mV typical (E grade, SO package) - ensures accurate threshold detection in precision level-shifting applications. |
Pinout & Package
MAX962ESA is housed in an 8-pin SO (Small Outline) package (package code S8-2), with exposed pad not present and RoHS-compliant per Maxim documentation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Comparator B Inverting Input (INB–) | Differential input node for second comparator; accepts Beyond-the-Rails voltages. |
| 2 | Comparator B Noninverting Input (INB+) | Differential input node for second comparator; matches INB– in voltage range and bias behavior. |
| 3 | GND | Analog/digital ground reference for both comparators and output stage. |
| 4 | Comparator A Inverting Input (INA–) | Differential input node for first comparator; electrically identical to INB–. |
| 5 | Comparator A Noninverting Input (INA+) | Differential input node for first comparator; matches INA– in performance. |
| 6 | VCC | Positive supply rail (2.7V–5.5V); powers both comparators and output drivers. |
| 7 | Comparator A Output (QA) | TTL/CMOS-compatible active-pull output; sinks/sources 4mA with rail proximity. |
| 8 | Comparator B Output (QB) | Independent TTL/CMOS-compatible output; no functional coupling to QA or control pins. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns typical ensures timing-critical decisions in <5ns windows (e.g., jitter measurement, pulse width discrimination). |
| Beyond-the-Rails™ input range | –0.1V to VCC + 0.1V enables direct interfacing with AC-coupled sensors or level-shifted signals without clamping diodes. |
| Internal 3.5mV hysteresis | Eliminates external hysteresis resistors and prevents chatter in noisy or slowly varying input conditions. |
| TTL/CMOS-compatible outputs | Direct connection to FPGA I/O banks or microcontroller GPIOs without level-shifting circuitry. |
| Low 5mA supply current per comparator | Enables dual-channel high-speed comparison in power-constrained portable systems (e.g., handheld test equipment). |
Applications
| GPS Receivers | High-Speed Sampling Circuits |
|---|---|
Use Scenario: Processing baseband IF signals with precise zero-crossing detection for carrier recovery and bit synchronization. IC Role / Device Role / Timing Role: Dual comparator performing simultaneous differential threshold detection on I/Q channels to generate clean clock-aligned strobes. Use Value: 4.5ns propagation delay minimizes timing skew between I/Q paths, preserving phase integrity critical for coherent demodulation. | Use Scenario: Digitizing analog waveforms at >100MSPS using flash ADC front-end sampling triggers. IC Role / Device Role / Timing Role: Generating precise, jitter-minimized sample-enable pulses from analog trigger thresholds. Use Value: 3.5mV internal hysteresis rejects broadband noise on trigger lines, preventing false sampling events without adding external filtering delay. |
| Threshold Detectors | Line Receivers |
Use Scenario: Monitoring multiple sensor outputs (e.g., temperature, pressure) for out-of-range alarms in industrial PLC modules. IC Role / Device Role / Timing Role: Dual independent comparator detecting upper/lower limits on separate analog inputs with rail-to-rail compatibility. Use Value: –0.1V to VCC + 0.1V input range accommodates sensor offsets and supply variations without external biasing networks. | Use Scenario: Receiving differential RS-422/RS-485 data streams in noisy factory-floor communication nodes. IC Role / Device Role / Timing Role: Converting differential line voltages into single-ended logic-level signals with minimal propagation delay skew. Use Value: Matched tPD+ and tPD– (0.3ns skew) ensures accurate data eye capture at multi-Mbps rates without added timing margin. |
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 |
|---|---|---|---|
| MAX962EUA-T | Identical electrical specs but in 8-pin μMAX® package (U8-1); same pinout as SO-8 except smaller footprint and thermal characteristics. | Preferred for space-constrained PCBs where thermal dissipation permits μMAX use; not drop-in due to different land pattern. | Select when board area is limited and thermal design accommodates μMAX package derating (330mW @ +70°C). |
| LMH7322MA/NOPB | 2.5ns propagation delay, higher supply current (12mA/comparator), no internal hysteresis, requires external hysteresis network. | Better suited for ultra-low-jitter applications where external component count is acceptable and faster response is mandatory. | Choose only if <3ns delay is required and system can support external hysteresis resistors and higher power budget. |
Compared with MAX962EUA-T, the MAX962ESA offers identical functionality in a standard SO-8 footprint compatible with legacy layouts and automated assembly; compared with LMH7322MA/NOPB, it trades 2ns speed for integrated hysteresis, lower power, and simpler BOM - making it optimal for robust, cost-sensitive high-speed thresholding.

FAQ
What is the operating temperature range for the MAX962ESA?
The MAX962ESA is specified for operation from –40°C to +85°C (E grade). This range is guaranteed per Maxim's datasheet Absolute Maximum Ratings and Electrical Characteristics tables, and applies to all SO-packaged E-grade variants including MAX962ESA, MAX961ESA, and MAX997ESA. No extended temperature versions exist for this SO-8 variant.
Does the MAX962ESA support shutdown mode?
No, the MAX962ESA does not support shutdown mode. Per the Selector Guide and Pin Configurations table, shutdown (SHDN) is only available on MAX961, MAX963, MAX964, and MAX997 - not on MAX962. The MAX962ESA draws 5mA per comparator continuously under normal operation and has no dedicated SHDN pin or internal shutdown circuitry.
What is the input common-mode voltage range of the MAX962ESA?
The MAX962ESA supports an input common-mode voltage range of –0.1V to VCC + 0.1V, as confirmed in the Electrical Characteristics table under "Input Common-Mode Voltage Range (VCMR)". This Beyond-the-Rails™ capability allows either input to be driven slightly below GND or above VCC without false output inversion, provided the other input remains within this range.
Can the MAX962ESA drive standard TTL loads directly?
Yes, the MAX962ESA can drive standard TTL loads directly. Its outputs source or sink 4mA while maintaining VOH ≥ VCC – 0.52V and VOL ≤ 0.52V (per Electrical Characteristics), meeting TTL VOH(min) = 2.4V and VOL(max) = 0.4V requirements at VCC = 5V. No external pull-up resistors are needed for TTL interfacing.
Is there a latch-enable function on the MAX962ESA?
No, the MAX962ESA does not include a latch-enable function. The Selector Guide explicitly states "No" under "Latch Enable" for MAX962, and the Pin Description table shows no LE or latch-related pins assigned to MAX962. Latch functionality is exclusive to MAX961 and MAX963 in this family.
