Product details
Overview
LMV762MAX from Texas Instruments is a dual-channel, low-voltage, precision comparator with push-pull output, designed for single-supply operation from 2.7 V to 5.25 V. It delivers 120 ns propagation delay at 50 mV overdrive, 0.2 mV typical input offset voltage, and 300 µA total supply current (both channels), enabling high-speed threshold detection in portable and battery-powered systems.
For engineers reviewing the LMV762MAX datasheet, LMV762MAX pinout, LMV762MAX application, or LMV762MAX equivalent, key selection considerations include its rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), 100 dB CMRR, 110 dB PSRR, and automotive-grade variant compatibility - all critical for noise-immune, low-power analog-to-digital decision circuits.
Technical Context
The LMV762MAX implements a CMOS-input, push-pull-output architecture that eliminates external pull-up resistors and supports direct interfacing with TTL/CMOS logic. Its dual independent comparators share only power rails, with no internal coupling or crosstalk specified.
It operates across −40°C to +125°C with guaranteed 1 mV max input offset voltage over temperature, 0.2 pA typical input bias current, and 5 ns max propagation delay skew between channels - enabling precise timing alignment in window or zero-crossing detection topologies.
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 single-supply systems without level-shifting. |
| Input Offset Voltage (Max) | 1 mV over −40°C to +125°C - ensures stable switching thresholds in automotive and industrial environments. |
| Propagation Delay | 120 ns at 50 mV overdrive - enables reliable sampling of signals up to ~4 MHz in high-speed comparator applications. |
| Supply Current (Total) | 550 µA typical at 5 V - balances speed and ultra-low power for always-on sensing in battery-constrained devices. |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply and common-mode noise, critical for accurate comparisons in noisy embedded systems. |
| Input Bias Current | 0.2 pA typical - permits use with megaohm-level resistor dividers and high-impedance sensor interfaces without error. |
| Output Type | Push-pull - drives high/low actively; no external pull-up required, simplifying PCB layout and reducing BOM count. |
Pinout & Package
LMV762MAX is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with body size 4.90 mm × 3.91 mm, optimized for automated assembly and thermal performance (RθJA = 190°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTA | Channel A Output | Active push-pull digital output; sinks or sources current without external components. |
| 2 - −INA | Channel A Inverting Input | High-impedance CMOS node; accepts analog signals within −0.3 V to VCC − 1.3 V common-mode range. |
| 3 - +INA | Channel A Noninverting Input | High-impedance CMOS node; paired with −INA for differential threshold comparison. |
| 4 - V− | Negative Power Terminal | Ground reference for single-supply operation; must be connected to system GND. |
| 5 - +INB | Channel B Noninverting Input | Independent input for second comparator; electrically isolated from Channel A inputs. |
| 6 - −INB | Channel B Inverting Input | Independent input for second comparator; enables dual-threshold or window detection. |
| 7 - OUTB | Channel B Output | Second independent push-pull output; supports asynchronous dual-comparator logic. |
| 8 - V+ | Positive Power Terminal | Primary supply pin; accepts 2.7 V–5.25 V; requires local 0.1 µF ceramic decoupling. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722QDR | Lower supply current (125 µA/ch), slower propagation delay (300 ns), no guaranteed 125°C operation. | Better suited for ultra-low-power, non-automotive applications where speed is secondary. | Select when extended temperature range and sub-200 ns timing are not required. |
| TLV3502IDR | Faster propagation delay (4.5 ns), higher supply current (8 mA/ch), rail-to-rail output but not rail-to-rail input. | Targeted at high-speed data acquisition, not precision thresholding with high-impedance sources. | Choose only when nanosecond response dominates over input bias current and power constraints. |
Compared with LMV762MAX, LMV722QDR trades speed and temperature range for lower quiescent power, while TLV3502IDR sacrifices input impedance and efficiency for raw speed - making LMV762MAX the optimal balance for precision, low-power, wide-temperature dual-comparator use cases.

FAQ
What is the maximum operating supply voltage for LMV762MAX?
The absolute maximum supply voltage (V+ – V−) for LMV762MAX is 5.5 V. However, the recommended operating range is 2.7 V to 5.25 V per the datasheet's Recommended Operating Conditions table. Exceeding 5.25 V may compromise parametric guarantees, and operation above 5.5 V risks permanent damage. LMV762MAX is rated for continuous operation at 5 V nominal, with full specification compliance across −40°C to +125°C.
Does LMV762MAX include a shutdown feature?
No, LMV762MAX does not include a shutdown pin. The shutdown function is present only on the LMV761 (single-channel) variant, as confirmed by the Pin Configuration and Functions section of the datasheet. LMV762MAX is a dual comparator without shutdown capability - all pins are dedicated to power, inputs, and outputs. This simplifies routing but means supply current remains active whenever powered.
What is the input common-mode voltage range for LMV762MAX at 5 V supply?
At VCC = 5 V, the input common-mode voltage range for LMV762MAX is −0.3 V to 3.8 V, as specified in the 5-V Electrical Characteristics table under CMVR. This range is defined for CMRR > 50 dB and applies across the full operating temperature range. The lower bound extends below ground, supporting AC-coupled inputs; the upper bound stops 1.2 V below VCC, requiring level-shifting for full rail-to-rail input signals.
Can LMV762MAX drive a 50-Ω transmission line directly?
No, LMV762MAX is not designed to drive 50-Ω loads continuously. Its output short-circuit current is rated at ±6 mA (sourcing/sinking), and output swing degrades significantly under heavy loads: at 4 mA sink, VOL rises to 250 mV. Driving 50 Ω at 5 V would require 100 mA - far exceeding safe limits. Use a dedicated line driver (e.g., SN65LVDS1) or buffer amplifier for such applications.
Is LMV762MAX pin-compatible with LMV762Q-Q1?
Yes, LMV762MAX and LMV762Q-Q1 share identical pinouts in SOIC (8-pin) and VSSOP packages, as confirmed by the Pin Functions for SOIC and VSSOP (Dual) table. Both use pins 1–8 for OUTA, −INA, +INA, V−, +INB, −INB, OUTB, and V+. However, LMV762Q-Q1 adds AEC-Q100 Grade 1 qualification and enhanced ESD robustness (HBM ±2000 V), while LMV762MAX is intended for industrial/commercial use.
