Product details
Overview
The 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), 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 MAX962EUA+ datasheet, MAX962EUA+ pinout, MAX962EUA+ application, or MAX962EUA+ equivalent, key selection criteria include propagation delay vs. overdrive, rail-to-rail input capability, output drive strength (4mA to within 0.52V of rails), supply current across temperature, and μMAX® package thermal performance.
Technical Context
The MAX962EUA+ implements a current-driven output stage enabling fast slew rates and rail-swing output compliance without external pull-ups. Its internal 3.5mV hysteresis eliminates need for external feedback resistors while preventing oscillation near trip points.
Unlike the latch-enabled MAX961/MAX963 or shutdown-capable MAX961/MAX963/MAX964/MAX997, the MAX962EUA+ has no shutdown or latch-enable functionality - it operates continuously with fixed dual-comparator topology and non-complementary outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns decision latency in timing-critical sampling paths |
| Supply Voltage Range | +2.7V to +5.5V - supports both 3V and 5V single-supply systems without level-shifting |
| Input Common-Mode Range | –0.1V to VCC + 0.1V - accepts signals beyond supply rails, simplifying sensor interface design |
| Output Drive Strength | Sinks or sources 4mA to within 0.52V of GND/VCC - directly drives CMOS/TTL loads without external buffers |
| Supply Current per Comparator | 5mA typical at VCC = 5V - balances speed and power for portable +5V applications |
| Input Offset Voltage | ±0.5mV typical (±2.0mV max) - ensures accurate threshold detection under varying common-mode conditions |
| Input Hysteresis | 3.5mV - provides noise immunity without external components in noisy industrial environments |
Pinout & Package
The MAX962EUA+ is housed in an 8-pin μMAX® package (pin-compatible with SO-8 but 30% smaller footprint and improved thermal resistance). The package is RoHS-compliant and rated for –40°C to +85°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– (Comparator A) | Inverting input for first comparator; accepts voltages down to –0.1V |
| 2 | IN+ (Comparator A) | Noninverting input for first comparator; supports Beyond-the-Rails operation |
| 3 | GND | Analog/digital ground reference; requires low-inductance PCB plane |
| 4 | IN– (Comparator B) | Inverting input for second comparator; electrically isolated from Channel A |
| 5 | IN+ (Comparator B) | Noninverting input for second comparator; independent signal path |
| 6 | VCC | Positive supply input; must be decoupled with 0.1µF ceramic capacitor adjacent to pin |
| 7 | Q (Comparator A Output) | TTL/CMOS-compatible active-high output; sinks/sources 4mA |
| 8 | Q (Comparator B Output) | TTL/CMOS-compatible active-high output; independent of Channel A output |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns typical ensures sub-5ns response in high-frequency sampling and clock recovery |

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 | Higher supply current (9mA/ch), no internal hysteresis, 2.5ns propagation delay, SO-8 only | Requires external hysteresis network; better suited for ultra-low-delay applications where power is secondary | Select when <2.5ns delay is mandatory and board area allows SO-8 + external resistors |
| ADCMP602BRMZ | 3.5ns delay, 5.5mA/ch, internal 3mV hysteresis, same μMAX-8 package, rail-to-rail inputs | Identical functional scope but different offset drift and PSRR specs; not drop-in due to different pinout (GND on Pin 3 vs. Pin 4) | Select when tighter offset drift (<1.5µV/°C) or higher PSRR (>60dB) is required; verify layout compatibility |
Compared with LMH7322MA/NOPB, the MAX962EUA+ trades 2ns of speed for integrated hysteresis and lower quiescent current; compared with ADCMP602BRMZ, it offers identical package size but differs in pin assignment and thermal coefficient behavior - requiring PCB redesign despite shared footprint dimensions.

FAQ
What is the maximum operating temperature range for the MAX962EUA+?
The MAX962EUA+ is specified for operation from –40°C to +85°C. This E-grade temperature range is guaranteed across all electrical parameters in the datasheet, including propagation delay, input offset voltage, and output drive capability. The device uses standard silicon process technology and does not support extended temperature grades like the MAX999AAUK+ variant.
Does the MAX962EUA+ support shutdown mode?
No, the MAX962EUA+ does not include a shutdown feature. Unlike the MAX961, MAX963, MAX964, or MAX997 variants, the MAX962EUA+ lacks a SHDN pin and remains fully active whenever powered. Its supply current remains at 5mA per comparator across the full temperature range, with no low-power standby state.
What is the input hysteresis value of the MAX962EUA+ and how is it implemented?
The MAX962EUA+ features a fixed 3.5mV internal hysteresis, implemented via on-chip circuitry that creates two distinct input trip points. This eliminates the need for external positive-feedback resistors and ensures consistent noise immunity across voltage and temperature. The hysteresis width is measured as the difference between upper and lower input-referred trip points under standard test conditions.
Can the MAX962EUA+ accept input voltages below ground or above VCC?
Yes, the MAX962EUA+ supports a Beyond-the-Rails™ input common-mode range of –0.1V to VCC + 0.1V. This allows direct interfacing with sensors, DACs, or other circuitry whose output swings slightly beyond the supply rails. Operation outside this range may cause saturation or increased propagation delay, but the device remains undamaged per absolute maximum ratings.
Is the MAX962EUA+ pin-compatible with other devices in the MAX96x family?
The MAX962EUA+ shares the same 8-pin μMAX® package footprint with the MAX961EUA+, MAX997EUA+, and MAX962ESA, but pin functions differ. Specifically, Pin 3 is GND for MAX962EUA+, whereas Pin 4 is GND for MAX961EUA+. This difference means the MAX962EUA+ is not pin-compatible with MAX961EUA+ or MAX997EUA+ - PCB layout must match the MAX962-specific pinout shown in the datasheet.
