Product details
Overview
MAX962EUA 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), ±3.5mV input-referred hysteresis, 5mA supply current per comparator, and Beyond-the-Rails™ input range extending 100mV beyond both rails - used in GPS receivers and high-speed sampling circuits.
For engineers reviewing the MAX962EUA datasheet, MAX962EUA pinout, MAX962EUA application, or MAX962EUA equivalent, key selection criteria include propagation delay skew (<0.3ns), rail-to-rail output drive capability (0.52V from GND/VCC), dual-channel independence, temperature-stable trip points (–40°C to +85°C), and μMAX® 8-pin package compatibility with space-constrained portable systems.
Technical Context
The MAX962EUA implements a current-driven output stage enabling fast slew rates and TTL/CMOS-compatible outputs that sink/source 4mA while staying within 0.52V of either rail. Its internal 3.5mV hysteresis eliminates external feedback resistors and prevents oscillation near trip points.
Unlike the latch-enabled MAX961/MAX963 or shutdown-capable MAX961/MAX964/MAX997, the MAX962EUA has no latch-enable or shutdown inputs - it operates continuously with fixed dual-comparator topology and no logic control pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision timing in high-speed threshold detection. |
| Supply Voltage Range | +2.7V to +5.5V - supports direct integration into 3V and 5V single-supply systems without level shifting. |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - allows input signals 100mV beyond supply rails, critical for sensor interfacing with offset voltages. |
| Output Drive Capability | Sinks/sources 4mA to within 0.52V of GND or VCC - eliminates need for external pull-up/pull-down resistors. |
| Supply Current per Comparator | 5mA typical at VCC = 5V - balances speed and power for battery-sensitive applications like portable GPS receivers. |
| Input-Referred Hysteresis | 3.5mV typical - ensures clean, bounce-free switching without external hysteresis components. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive-adjacent embedded environments. |
Pinout & Package
MAX962EUA is housed in an 8-pin μMAX® package (package code U8-1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal performance. The μMAX® footprint is pin-compatible with SO-8 but offers 55% smaller area.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– (Comparator A) | Inverting input for first comparator channel; accepts Beyond-the-Rails™ voltage range. |
| 2 | IN+ (Comparator A) | Noninverting input for first comparator channel; matched impedance and bias to Pin 1. |
| 3 | IN– (Comparator B) | Inverting input for second independent comparator channel; electrically isolated from Channel A. |
| 4 | IN+ (Comparator B) | Noninverting input for second comparator channel; supports independent threshold setting. |
| 5 | GND | Analog/digital ground reference shared by both comparators; requires low-inductance PCB connection. |
| 6 | VCC | Positive supply input (2.7V–5.5V); must be decoupled with 0.1μF ceramic capacitor placed adjacent to Pin 6. |
| 7 | Q (Comparator A Output) | TTL/CMOS-compatible active-high output; drives loads directly without external pull-ups. |
| 8 | Q (Comparator B Output) | Independent TTL/CMOS-compatible output for second channel; no crosstalk or shared logic resources. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns typical ensures precise timing alignment in >200MHz sampling windows. |
| Beyond-the-Rails™ input range | –0.1V to VCC + 0.1V enables direct interface with sensors or DACs exceeding supply limits. |
| Internal 3.5mV hysteresis | Eliminates external resistor networks and prevents chatter during slow or noisy input transitions. |
| Rail-to-rail output drive | 0.52V from GND/VCC at 4mA load removes dependency on pull-up resistors and reduces BOM count. |
| Dual independent channels | No shared bias, latch, or shutdown circuitry - each comparator operates autonomously with full spec compliance. |
Applications
| GPS Receiver Front-End | High-Speed Line Receiver |

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 |
|---|---|---|---|
| LMH7322MA/NOPB | 2.2ns propagation delay, 12mA supply current, no internal hysteresis, SO-8 package. | Requires external hysteresis resistors; better suited for ultra-low-delay applications where power is secondary. | Select when sub-3ns timing is mandatory and board space allows for external components. |
| ADCMP602BRMZ | 3.5ns propagation delay, 10mA supply current, 2.5mV hysteresis, 8-lead MSOP package. | Higher supply current and different pinout; lacks Beyond-the-Rails™ input range (limited to GND–VCC). | Choose for legacy MSOP footprint compatibility and tighter hysteresis tolerance, but verify input voltage margins. |
Compared with LMH7322MA/NOPB and ADCMP602BRMZ, the MAX962EUA delivers optimal balance of speed (4.5ns), power (5mA), integrated hysteresis (3.5mV), and input flexibility (Beyond-the-Rails™), making it uniquely suitable for compact, single-supply portable systems requiring deterministic switching without external components.

FAQ
What is the operating temperature range for the MAX962EUA?
The MAX962EUA is specified for operation from –40°C to +85°C (E grade). All electrical characteristics in its datasheet are guaranteed across this full industrial temperature range, with production testing performed at +25°C and design validation covering min/max extremes.
Does the MAX962EUA support shutdown mode?
No, the MAX962EUA does not include a shutdown input or low-power sleep state. Unlike the MAX961/MAX964/MAX997 variants, it operates continuously with a fixed 5mA per comparator supply current - optimized for always-on high-speed detection rather than intermittent duty cycles.
What package type is used for the MAX962EUA?
The MAX962EUA uses the 8-pin μMAX® package (U8-1), a miniature 3mm × 3mm surface-mount outline with exposed thermal pad. It is not pin-compatible with SO-8 despite identical pin count, due to different pad layout and pitch - land pattern 90-0092 must be used.
Can the MAX962EUA accept input voltages beyond the supply rails?
Yes, the MAX962EUA supports Beyond-the-Rails™ input operation: either input can swing from –0.1V to VCC + 0.1V. This allows direct interfacing with sensors or DACs whose outputs exceed the comparator's supply range, without external level-shifting circuitry.
Is there internal hysteresis in the MAX962EUA, and what is its value?
Yes, the MAX962EUA includes fixed internal hysteresis of 3.5mV (typical), referenced to the input. This eliminates the need for external positive-feedback resistors and ensures clean, chatter-free switching even with slow-moving or noisy input signals near the threshold point.
