Product details
Overview
LMV762QMM/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. It operates from 2.7 V to 5.25 V and supports automotive-grade temperature range (−40°C to +125°C), enabling use in battery-powered sensor monitoring and high-speed window detection circuits.
For engineers reviewing the LMV762QMM/NOPB datasheet, LMV762QMM/NOPB pinout, LMV762QMM/NOPB application, or LMV762QMM/NOPB equivalent, key selection criteria include its rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), CMRR of 100 dB, PSRR of 110 dB, and AEC-Q100 Grade 1 qualification - critical for automotive powertrain and ADAS subsystems requiring stable threshold detection under noisy supply conditions.
Technical Context
The LMV762QMM/NOPB implements a CMOS-input, push-pull-output architecture eliminating external pull-up resistors and enabling direct interfacing with CMOS/TTL logic. Its dual independent channels share only the V+ and V− supply rails, with no internal cross-coupling between IN/OUT paths.
Each channel features matched input bias current (0.2 pA typical), enabling high-impedance sensing without resistor balancing, and supports shutdown-free operation - unlike the LMV761, this variant lacks a shutdown pin and is optimized for always-on precision comparison in safety-critical automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - supports single-supply operation across 3.3 V and 5 V systems 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 management sensors. |
| Propagation Delay | 120 ns at 50 mV overdrive - enables reliable sampling of fast analog events such as motor phase transitions or fault pulses. |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply ripple and common-mode noise in electric vehicle DC-DC converters and inverter gate drivers. |
| Input Bias Current | 0.2 pA typical - permits use with >10 MΩ source impedances in thermistor or photodiode front-ends without gain error. |
| Output Type | Push-pull - drives loads directly up to ±4 mA without external pull-up, reducing BOM count in compact ECU designs. |
| Operating Temperature | −40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm), thin-profile surface-mount, compatible with automated SMT assembly and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Channel A output | Active-high/low push-pull output; sinks or sources up to 4 mA; no external pull-up required. |
| 2 - −INA | Channel A inverting input | High-impedance CMOS node; accepts signals down to −0.3 V below V− (ground) in single-supply mode. |
| 3 - +INA | Channel A noninverting input | Matches −INA in bias current and offset; enables differential or single-ended reference configurations. |
| 4 - V− | Negative supply terminal | Reference ground for both channels; must be connected to system GND or negative rail. |
| 5 - +INB | Channel B noninverting input | Independent of Channel A; supports dual-threshold or redundant comparison architectures. |
| 6 - −INB | Channel B inverting input | Electrically isolated from Channel A inputs; enables independent hysteresis tuning per channel. |
| 7 - OUTB | Channel B output | Functionally identical to OUTA; supports parallel or complementary logic outputs. |
| 8 - V+ | Positive supply terminal | Supplies both comparators; requires local 0.1 µF ceramic decoupling to minimize switching transients. |
