Product details
Overview
The MAX962EUA-T 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 sinking/sourcing 4mA to within 0.52V of GND/VCC - used in GPS receivers and high-speed sampling circuits.
For engineers reviewing the MAX962EUA-T datasheet, MAX962EUA-T pinout, MAX962EUA-T application, or MAX962EUA-T equivalent, key selection considerations include propagation delay skew (<0.3ns), differential input impedance (8kΩ), input-referred hysteresis (3.5mV), operating temperature range (–40°C to +85°C), and μMAX-8 package compatibility with space-constrained portable systems.
Technical Context
The MAX962EUA-T implements a current-driven output stage enabling rapid slew rates while maintaining low static power; its internal hysteresis eliminates need for external feedback resistors. Unlike latch-equipped variants (e.g., MAX961/MAX963), it lacks latch-enable and shutdown functionality - confirmed by selector guide and pin configuration tables.
It uses a precision input stage with front-to-back diode protection (±3VF limit) and 200Ω series resistors, supporting rail-to-rail common-mode operation. Input bias current is ±15µA (typ), input offset voltage is ±0.5mV (typ), and differential propagation delay between channels is ≤0.3ns - critical for matched timing in dual-channel threshold detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typ at 5mV overdrive - enables sub-5ns decision latency in high-speed data acquisition. |
| 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 without level-shifting. |
| Output Drive Capability | Sinks/sources 4mA to within 0.52V of rails - eliminates need for external pull-up/pull-down resistors. |
| Input-Referred Hysteresis | 3.5mV - suppresses noise-induced oscillation at threshold crossings without external components. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive under-hood environments. |
| Supply Current per Comparator | 5mA typ at VCC = 5V - balances speed and power efficiency for battery-sensitive applications. |
Pinout & Package
The MAX962EUA-T is housed in an 8-pin μMAX® package (package code U8-1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. This RoHS-compliant, lead-free package supports high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– (Comparator A) | Inverting input for first comparator channel; accepts Beyond-the-Rails voltages. |
| 2 | IN+ (Comparator A) | Noninverting input for first comparator channel; matched impedance with Pin 1. |
| 3 | GND | Analog/digital ground reference; must connect to low-inductance ground plane. |
| 4 | IN– (Comparator B) | Inverting input for second comparator channel; electrically isolated from Channel A. |
| 5 | IN+ (Comparator B) | Noninverting input for second comparator channel; supports independent signal routing. |
| 6 | VCC | Positive supply input; requires local 0.1µF ceramic decoupling capacitor. |
| 7 | Q (Comparator A Output) | TTL/CMOS-compatible active-high output; drives logic inputs directly. |
| 8 | Q (Comparator B Output) | TTL/CMOS-compatible active-high output; independent timing path from Pin 7. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High-Speed Operation | 4.5ns propagation delay enables real-time response in >200MHz sampling systems. |
| Beyond-the-Rails Input Range | –0.1V to VCC + 0.1V input capability eliminates level-shifters in mixed-supply systems. |
| Internal Hysteresis | 3.5mV fixed hysteresis prevents chatter during slow or noisy threshold transitions. |
| Rail-to-Rail Output Drive | Outputs swing to within 0.52V of GND/VCC at 4mA load - compatible with 3.3V/5V logic families. |
| Low-Power High-Speed Tradeoff | 5mA per comparator at 5V supply delivers best-in-class speed/power ratio for dual comparators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual ultra-high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH7322MA/NOPB | Higher supply current (9.5mA), no internal hysteresis, requires external feedback network. | Requires board redesign for hysteresis; better suited for adjustable threshold applications. | Select when programmable hysteresis or higher drive strength (50mA) is required. |
| ADCMP602BRMZ-REEL | 3.5ns propagation delay, 3.3V-only supply, no Beyond-the-Rails input (0V to VCC). | Limited to single-supply 3.3V systems; cannot accept sub-GND inputs. | Select when minimum propagation delay is critical and input range is constrained to 0V–3.3V. |
Compared with LMH7322MA/NOPB and ADCMP602BRMZ-REEL, the MAX962EUA-T uniquely combines 4.5ns speed, internal 3.5mV hysteresis, and Beyond-the-Rails input operation in a single 8-pin μMAX package - simplifying layout and reducing BOM count for portable and GPS timing designs.

FAQ
What is the maximum operating supply voltage for the MAX962EUA-T?
The MAX962EUA-T supports a supply voltage range of +2.7V to +5.5V. Absolute maximum rating is +6V on VCC relative to GND. Exceeding +5.5V may degrade long-term reliability or violate guaranteed specifications - always operate within the 2.7V–5.5V range for full performance compliance per the datasheet.
Does the MAX962EUA-T include shutdown or latch functionality?
No, the MAX962EUA-T does not include shutdown or latch-enable features. Per the selector guide and pin configuration table, only MAX961/MAX963/MAX964/MAX997 support shutdown, and only MAX961/MAX963 support latch-enable. The MAX962EUA-T is a dual comparator with fixed functionality: two independent channels, each with IN+, IN–, and Q pins.
What is the input-referred hysteresis value for the MAX962EUA-T?
The MAX962EUA-T has a fixed input-referred hysteresis of 3.5mV, as specified in the Electrical Characteristics table under "Input-Referred Hysteresis." This value is inherent to the device architecture and requires no external components - it stabilizes switching behavior during slow or noisy input transitions.
Can the MAX962EUA-T accept input voltages below ground or above VCC?
Yes, the MAX962EUA-T supports a Beyond-the-Rails™ input common-mode range of –0.1V to VCC + 0.1V. This allows valid operation with inputs as low as 100mV below GND or 100mV above VCC - verified in Absolute Maximum Ratings and Electrical Characteristics sections for all E-grade μMAX-packaged variants including MAX962EUA-T.
What package type and dimensions does the MAX962EUA-T use?
The MAX962EUA-T uses the 8-pin μMAX® package (package code U8-1), measuring 3.0mm × 3.0mm × 0.8mm with an exposed thermal pad. It is RoHS-compliant and lead-free ("+" suffix implied), and its land pattern is documented in Maxim's package drawing 21-0036 and footprint 90-0092.
