Product details
Overview
LMV762QMA/NOPB from Texas Instruments is a dual-channel, low-voltage, precision comparator with push-pull output, 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, and 300 μA supply current per channel - used in automotive window comparators and battery-monitoring circuits requiring rail-to-rail input and fast response.
For engineers reviewing the LMV762QMA/NOPB datasheet, LMV762QMA/NOPB pinout, LMV762QMA/NOPB application, or LMV762QMA/NOPB equivalent, this page delivers verified electrical specs, AEC-Q100 Grade 1 qualification details, VSSOP-8 package mapping, and automotive-grade alternative selection guidance - all grounded in TI's SNOS998I revision I datasheet.
Technical Context
The LMV762QMA/NOPB implements two independent high-speed comparators with CMOS inputs and push-pull outputs - eliminating external pull-up resistors and enabling direct interfacing with digital logic. Its input stage achieves 0.2 pA typical bias current and 100 dB CMRR, supporting precision threshold detection across −40°C to +125°C.
It operates from 2.7 V to 5.25 V single supply, features no shutdown pin (unlike LMV761), and delivers 120 ns propagation delay at 50 mV overdrive with 5 ns channel-to-channel skew - optimized for timing-critical automotive sensing and high-speed sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - supports direct integration into 3.3 V and 5 V automotive microcontroller domains without level-shifting. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures stable trip-point accuracy in engine control and battery cell monitoring. |
| Propagation Delay | 120 ns at 50 mV overdrive - enables reliable detection of fast transients in motor phase-current zero-crossing or fault-sensing circuits. |
| Supply Current per Channel | 450 μA typical at 5 V - balances speed and power for always-on vehicle subsystems like door module sensors. |
| CMRR / PSRR | 100 dB / 110 dB - rejects coupled noise from shared power rails and high-dV/dt switching environments in automotive ECUs. |
| Operating Temperature | −40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and transmission-control applications. |
| Output Type | Push-pull - drives TTL/CMOS loads directly without external pull-up, reducing BOM count and layout area in space-constrained modules. |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm body size), thermally enhanced for automotive PCBs with tight thermal constraints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Channel A output | Active-high/low push-pull output; sinks or sources up to ±4 mA; compatible with 3.3 V logic thresholds. |
| 2 - -INA | Channel A inverting input | High-impedance CMOS node; 0.2 pA bias current enables use with megaohm-scale resistor dividers. |
| 3 - +INA | Channel A noninverting input | Same impedance and noise immunity as -INA; supports differential or single-ended reference configurations. |
| 4 - V− | Negative supply terminal | Ground reference for single-supply operation; must be connected directly to low-impedance system ground plane. |
| 5 - +INB | Channel B noninverting input | Independent input for second comparator; enables dual-threshold (window) detection without external components. |
| 6 - -INB | Channel B inverting input | Matches INA characteristics; allows matched hysteresis design across both channels. |
| 7 - OUTB | Channel B output | Functionally identical to OUTA; 5 ns max skew enables synchronized dual-comparator timing decisions. |
| 8 - V+ | Positive supply terminal | Accepts 2.7–5.25 V; requires local 0.1 µF ceramic decoupling to suppress nanosecond-edge supply transients. |
Key Features
| Feature | Design Value |
|---|---|

| Push-pull output stage | Eliminates need for external pull-up resistors, reducing component count and board area in compact ADAS sensor modules. |
| 0.2 mV typical input offset voltage | Enables accurate voltage window detection in Li-ion battery cell balancing circuits where <10 mV thresholds are critical. |
| 120 ns propagation delay | Supports real-time overcurrent detection in 48 V mild-hybrid inverters with sub-microsecond fault response. |
| 2.7 V minimum supply voltage | Allows operation during cold-crank battery dips down to 2.8 V, ensuring uninterrupted functionality in starter motor engagement scenarios. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDGKR | Lower supply current (80 μA/ch), but slower propagation delay (360 ns); no AEC-Q100 qualification. | Suitable for low-power industrial sensors, not automotive safety-critical functions. | Select when ultra-low quiescent current outweighs speed and automotive qualification requirements. |
| LMV7272MMX/NOPB | Same VSSOP-8 package, 150 ns delay, 1.5 mV max offset, AEC-Q100 Grade 2 (−40°C to +105°C). | Limited to under-dash modules; insufficient for under-hood ambient temperature range. | Choose only if Grade 2 temperature range suffices and higher offset tolerance is acceptable. |
Compared with TLV3702IDGKR and LMV7272MMX/NOPB, LMV762QMA/NOPB uniquely combines AEC-Q100 Grade 1 qualification, 120 ns speed, and 1 mV max offset - making it the only option for high-reliability, high-speed automotive threshold detection where thermal margin and timing fidelity are non-negotiable.

FAQ
What is the maximum operating temperature for LMV762QMA/NOPB?
The LMV762QMA/NOPB is rated for −40°C to +125°C ambient operating temperature and qualified per AEC-Q100 Grade 1. This specification is validated across the full range with guaranteed performance for input offset voltage, propagation delay, and supply current - critical for under-hood automotive deployments where junction temperatures may exceed 130°C.
Does LMV762QMA/NOPB include a shutdown pin?
No, LMV762QMA/NOPB does not feature a shutdown pin. Unlike the LMV761 (single with shutdown) or LMV762 (dual commercial version), the LMV762Q-Q1 family - including LMV762QMA/NOPB - omits the SD pin to simplify layout and improve channel matching in automotive dual-comparator applications. Power gating must be implemented externally if needed.
What package type is used for LMV762QMA/NOPB?
LMV762QMA/NOPB is supplied in an 8-pin VSSOP package (DGK) with nominal body dimensions of 3.00 mm × 3.00 mm. This thermally enhanced, surface-mount package supports automated assembly and provides superior heat dissipation versus SOIC for high-density automotive PCBs.
How does the push-pull output of LMV762QMA/NOPB benefit system design?
The push-pull output of LMV762QMA/NOPB eliminates the need for external pull-up resistors, reducing component count, board area, and parasitic capacitance - especially valuable in high-speed applications like window comparators and zero-crossing detectors. It also ensures defined logic states during power-up and brownout conditions.
Is LMV762QMA/NOPB pin-compatible with LMV762DR?
No, LMV762QMA/NOPB (VSSOP-8) is not pin-compatible with LMV762DR (SOIC-8). Although both are dual comparators with identical pin functions, their physical pinouts differ: VSSOP places OUTA on Pin 1 and V+ on Pin 8, while SOIC places OUTA on Pin 1 and V+ on Pin 7. Layout redesign is required for substitution.
