Product details
Overview
The MAX962ESA+TG002 from Maxim Integrated is a dual ultra-high-speed comparator optimized for single +3V or +5V operation, featuring 4.5ns propagation delay (5mV overdrive), ±3.5mV input-referred hysteresis, and Beyond-the-Rails™ input range extending 100mV beyond both rails. It drives TTL/CMOS loads with 4mA sink/source capability to within 0.52V of GND/VCC and consumes 5mA per comparator - used in GPS receivers, high-speed sampling circuits, and threshold discriminators.
For engineers reviewing the MAX962ESA+TG002 datasheet, MAX962ESA+TG002 pinout, MAX962ESA+TG002 application, or MAX962ESA+TG002 equivalent, key selection criteria include propagation delay vs. overdrive, rail-to-rail input common-mode range, output drive strength at 3V/5V, supply current across temperature, and absence of latch/shutdown features compared to MAX961/MAX963/MAX997.
Technical Context
This dual comparator lacks latch-enable and shutdown inputs - distinguishing it from MAX961/MAX963/MAX964/MAX997 - and operates exclusively in active mode. Its internal hysteresis (3.5mV) eliminates external feedback resistors and prevents oscillation near trip points.
The current-driven output stage delivers fast slew rates but exhibits linear dependence on capacitive load; propagation delay skew between channels is guaranteed ≤0.3ns, and differential input impedance is 8kΩ with 130kΩ common-mode impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5ns typical at 5mV overdrive - enables sub-5ns timing-critical decisions in sampling or clock recovery |
| Supply Current per Comparator | 5mA at VCC = 5V - supports low-power portable systems without shutdown mode |
| Input Common-Mode Range | -0.1V to VCC + 0.1V - accepts signals beyond supply rails, simplifying sensor interface design |
| Output Drive Capability | Sinks/sources 4mA to within 0.52V of GND/VCC - directly interfaces TTL/CMOS without pull-up resistors |
| Input-Referred Hysteresis | 3.5mV - ensures clean switching without external hysteresis components |
| Input Offset Voltage | ±1.5mV typical - maintains accuracy in precision threshold detection |
| Operating Temperature | -40°C to +85°C - qualified for industrial embedded environments |
Pinout & Package
MAX962ESA+TG002 is housed in an 8-pin SO (Small Outline) package with exposed pad, compatible with standard SOIC-8 footprints and RoHS-compliant lead-free finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INB− | Inverting input for comparator B - accepts signals up to 100mV beyond rails |
| 2 | INB+ | Noninverting input for comparator B - differential pair with INB− defines B's decision threshold |
| 3 | INA− | Inverting input for comparator A - independent channel with same rail-exceeding range |
| 4 | INA+ | Noninverting input for comparator A - forms high-speed differential sensing path |
| 5 | GND | Analog/digital ground reference - must connect to low-inductance ground plane |
| 6 | VCC | Positive supply input (2.7V–5.5V) - requires local 0.1µF ceramic decoupling |
| 7 | QA | TTL/CMOS-compatible output for comparator A - sinks/sources 4mA, rail-swing limited to 0.52V |
| 8 | QB | TTL/CMOS-compatible output for comparator B - electrically identical to QA, no cross-talk guarantee |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 4.5ns typical enables timing-critical applications like GPS baseband sampling and zero-crossing detection |
| Beyond-the-Rails™ input range | Accepts inputs from -0.1V to VCC + 0.1V - eliminates level-shifting for battery-supplied sensors |
| TTL/CMOS-compatible outputs | Direct logic interfacing without external pull-ups - reduces BOM count and layout area |
| Internal 3.5mV hysteresis | Prevents chatter near thresholds - removes need for external hysteresis resistors and saves PCB space |
| Low 5mA supply current | Enables dual-channel high-speed comparison in power-constrained portable systems |
Applications
| GPS Receivers | High-Speed Sampling Circuits |
|---|---|
Use Scenario: Converting analog IF or baseband signals to digital logic levels for correlation and timing recovery in L1/L2 band receivers. IC Role / Device Role / Timing Role: Dual high-speed comparator performing simultaneous threshold detection on I/Q channels with sub-5ns latency. Use Value: 4.5ns propagation delay and 0.3ns channel-to-channel skew preserve signal integrity during symbol timing estimation. | Use Scenario: Digitizing fast transient waveforms in oscilloscopes, time-of-flight sensors, or RF envelope detectors. IC Role / Device Role / Timing Role: Window comparator or strobed sampler trigger generator using precise, hysteresis-stabilized thresholds. Use Value: 3.5mV internal hysteresis rejects noise-induced false triggers while maintaining nanosecond-level timing resolution. |
| Threshold Detectors/Discriminators | Line Receivers |

IC Role / Device Role / Timing Role: High-gain, low-delay comparator reconstructing logic states from degraded analog waveforms. Use Value: 5mA output drive sustains signal integrity into 50Ω loads or long traces, while 4.5ns delay minimizes jitter accumulation. |
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 | Same electrical specs, but in 8-pin μMAX® package (3mm × 3mm) vs. SOIC-8 (5mm × 4mm) | Better suited for space-constrained PCBs; thermal resistance higher (330mW/°C vs. 471mW/°C) | Select when board area is critical and thermal margin permits |
| LMH7322MA/NOPB | 4.5ns delay, 6mA supply current, rail-to-rail inputs, but no internal hysteresis and different pinout | Requires external hysteresis resistors; not drop-in replaceable due to pin assignment and feature set | Choose only if hysteresis is implemented externally and footprint redesign is acceptable |
Compared with MAX962ESA+TG002, the μMAX variant offers identical performance in a smaller footprint but reduced power dissipation capability, while LMH7322 demands layout changes and external components to match hysteresis functionality - making MAX962ESA+TG002 optimal for drop-in, low-risk, space-tolerant designs requiring integrated hysteresis.

FAQ
What is the operating supply voltage range for MAX962ESA+TG002?
The MAX962ESA+TG002 operates from 2.7V to 5.5V DC on VCC relative to GND. This range supports both +3V and +5V single-supply systems without level translation. The device maintains specified propagation delay, output drive, and input common-mode range across this full voltage span, as confirmed in the Electrical Characteristics table under "Supply Voltage" (VCC) with min/max values of 2.7V and 5.5V.
Does MAX962ESA+TG002 include shutdown or latch-enable functionality?
No, MAX962ESA+TG002 does not include shutdown or latch-enable inputs. Unlike MAX961/MAX963/MAX964/MAX997, the MAX962 variant is designed as a fixed-function dual comparator with no control pins for power management or output latching. Its pinout contains only two comparator input pairs, two outputs, VCC, and GND - confirmed in the Pin Configurations section and Selector Guide table where "SHUTDOWN" and "LATCH ENABLE" columns show "No" for MAX962.
What is the input common-mode voltage range of MAX962ESA+TG002?
The MAX962ESA+TG002 features a Beyond-the-Rails™ input common-mode range of -0.1V to VCC + 0.1V. This means either input (INA+, INA−, INB+, INB−) can be driven 100mV below GND or 100mV above VCC without damage or false output inversion - provided the other input remains within that same range. This specification is explicitly stated in the General Description and verified in the Electrical Characteristics table under "Input Common-Mode Voltage Range" (VCMR).
How much hysteresis does MAX962ESA+TG002 provide, and is it internal or external?
MAX962ESA+TG002 provides 3.5mV of input-referred hysteresis, and it is fully internal - no external resistors required. This fixed hysteresis eliminates oscillation near trip points and is confirmed in the Features list ("3.5mV Internal Hysteresis for Clean Switching") and Electrical Characteristics table under "Input-Referred Hysteresis". The hysteresis width equals the difference between upper and lower trip points, enabling robust threshold detection in noisy environments.
What package type and RoHS status does MAX962ESA+TG002 use?
MAX962ESA+TG002 uses an 8-pin SO (Small Outline) package with exposed pad, designated as "SO" in the Ordering Information table and "S8-2" in Package Information. The "+" suffix in the part number indicates lead(Pb)-free and RoHS-compliant construction, consistent with Maxim's packaging nomenclature where "+" denotes RoHS compliance per the datasheet footnote on page 1.
