Product details
Overview
LMV761MF/NOPB from Texas Instruments is a single-channel, low-voltage precision comparator with push-pull output and active-low shutdown pin, designed for battery-powered systems requiring 0.2 mV input offset voltage, 120 ns propagation delay at 50 mV overdrive, and 300 µA supply current at 5 V. It operates from 2.7 V to 5.25 V and supports −40°C to +125°C ambient temperature in portable instrumentation and scanner threshold detection.
For engineers reviewing the LMV761MF/NOPB datasheet, LMV761MF/NOPB pinout, LMV761MF/NOPB application, or LMV761MF/NOPB equivalent, key selection considerations include shutdown-enabled power gating, rail-to-rail output swing without pull-up, CMOS input bias current below 0.2 pA, and compatibility with 2.7-V/5-V single-supply systems.
Technical Context
The LMV761MF/NOPB implements a CMOS-input, push-pull-output architecture that eliminates external pull-up resistors and enables direct interfacing with digital logic. Its internal hysteresis-free design allows configurable external hysteresis via positive feedback, supporting precise zero-crossing and window detection.
Shutdown functionality is implemented via an active-low SD pin with logic thresholds proportional to VCC and absolute maximum rating of 5.5 V, enabling 5-V control signals even when VCC = 2.7 V. The device enters high-impedance output state with 20 nA supply leakage upon shutdown activation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures stable decision thresholds across automotive and industrial temperature ranges |
| Propagation Delay | 120 ns at 50 mV overdrive, 5 V supply - enables high-speed sampling in ADC front-ends and line receivers |
| Supply Current | 225–700 µA at 5 V - balances speed and ultra-low power for always-on sensor monitoring |
| Input Bias Current | 0.2 pA typical - permits use with >10 MΩ source impedances without offset error degradation |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply and common-mode noise in noisy embedded environments |
| Output Type | Push-pull - drives TTL/CMOS loads directly; no external pull-up required for logic-level compatibility |
| Shutdown Leakage | 0.2 µA supply current, 0.2 µA output leakage - maintains system-level sleep current budgets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDBVR | Lower supply current (170 nA), no shutdown pin, 360 ns propagation delay, 2.7–5.5 V supply | Better for ultra-low-power always-on sensing; unsuitable where fast response or shutdown control is required | Select TLV3691IDBVR only when nanowatt operation outweighs speed and controllability needs |
| LMV7215MF/NOPB | Higher speed (4.5 ns delay), rail-to-rail input, no shutdown, 2.7–5.5 V, 1.2 mV max offset | Preferred for high-frequency line receivers or clock/data recovery; lacks power-gating capability | Choose LMV7215MF/NOPB when propagation delay < 5 ns is mandatory and shutdown is unnecessary |
Compared with TLV3691IDBVR and LMV7215MF/NOPB, LMV761MF/NOPB uniquely balances sub-millivolt precision, 120 ns speed, and active shutdown in a 6-pin SOT-23-making it optimal for battery-sensitive, thermally demanding, and digitally controlled analog thresholding.

FAQ
What is the maximum operating supply voltage for LMV761MF/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV761MF/NOPB 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 long-term reliability or parametric performance, and operation above 5.5 V risks permanent damage. LMV761MF/NOPB must not be operated outside these limits in production designs.
Does LMV761MF/NOPB require an external pull-up resistor on its output?
No, LMV761MF/NOPB does not require an external pull-up resistor because it features a push-pull output stage. This architecture actively drives both high and low logic states, enabling direct interface with TTL and CMOS inputs. The output can source up to 4 mA and sink up to 4 mA at 5 V, delivering rail-to-rail swing from V− to V+ without external components - a key differentiator from open-drain comparators.
How does the shutdown pin (SD) function on LMV761MF/NOPB?
The SD pin on LMV761MF/NOPB is an active-low control input. When pulled low (≤0.8 V), it disables the comparator core, placing the OUT pin in high-impedance state and reducing total supply current to 20 nA. When driven high (≥2.0 V at 5 V VCC), normal operation resumes with 4 µs typical turn-on time. The SD pin accepts up to 5.5 V regardless of VCC, allowing 5-V logic control of lower-voltage systems.
What is the input common-mode voltage range for LMV761MF/NOPB at 5 V supply?
At V+ = 5 V, the input common-mode voltage range (CMVR) for LMV761MF/NOPB is −0.3 V to 3.8 V, specified for CMRR > 50 dB. This means both +IN and −IN can operate down to 0.3 V below ground (with appropriate negative bias) and up to 1.2 V below V+, supporting true single-supply operation with signals near ground or mid-rail. Operation outside this range degrades CMRR and may cause invalid output behavior.
Is LMV761MF/NOPB qualified for automotive applications?
LMV761MF/NOPB itself is not AEC-Q100 qualified; however, it shares the same silicon die and core architecture with the LMV762Q-Q1, which is explicitly qualified for Automotive Grade 1 (−40°C to +125°C) per AEC-Q100. While LMV761MF/NOPB is intended for industrial and portable applications, its electrical specs, thermal performance, and package construction align closely with automotive-grade variants - making it suitable for non-safety-critical automotive subsystems where formal qualification is not mandated.
