Product details
Overview
LMV761MFX/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 typical 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 range in 6-pin SOT-23 packaging.
For engineers reviewing the LMV761MFX/NOPB datasheet, LMV761MFX/NOPB pinout, LMV761MFX/NOPB application, or LMV761MFX/NOPB equivalent, key selection criteria include shutdown-enabled power gating, rail-to-rail input common-mode range (−0.3 V to 3.8 V at 5 V), push-pull output eliminating external pull-up resistors, and guaranteed 1 mV max VOS over temperature.
Technical Context
The LMV761MFX/NOPB implements a CMOS-input, push-pull-output architecture enabling direct interfacing with logic families without external biasing. Its shutdown mode reduces supply current to 20 nA while placing the output in high-impedance state - critical for ultra-low-power wake-up circuits.
It features 100 dB CMRR and 110 dB PSRR across 2.7–5 V supply range, ensuring stable operation under noisy supply conditions. Input bias current remains below 50 pA (max) over temperature, supporting high-impedance sensor interfaces and RC timing networks without error drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage (VOS) | 0.2 mV typ / 1 mV max over −40°C to +125°C - enables accurate threshold detection in precision analog monitoring |
| Propagation Delay | 120 ns typ at 50 mV overdrive, RL = 5.1 kΩ, CL = 50 pF - supports high-speed zero-crossing and sampling up to ~4 MHz |
| Supply Current | 225–700 µA at 5 V - scales with supply voltage and temperature; <300 µA typical for portable system battery life optimization |
| Input Common-Mode Range | −0.3 V to 3.8 V at 5 V supply - includes ground-referenced inputs and supports single-supply operation with rail-to-rail sensing |
| Output Type | Push-pull (no external pull-up required) - drives TTL/CMOS loads directly; VOH = V+ − 0.1 V, VOL = 120 mV max at −4 mA sink |
| Shutdown Current | 20 nA max - reduces system standby power by >99.9% vs active mode; SD pin accepts 5.5 V logic independent of VCC |

Pinout & Package
LMV761MFX/NOPB is packaged in a 6-pin SOT-23 (DBV) with body size 2.90 mm × 1.60 mm, optimized for space-constrained portable PCBs. Thermal resistance θJA = 265°C/W enables operation up to 125°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+IN) | Noninverting input | High-impedance CMOS node; accepts signals down to −0.3 V below V− (ground) for true single-supply compatibility |
| 2 (V−) | Negative power terminal | Ground reference for single-supply operation; must be connected to system GND |
| 3 (−IN) | Inverting input | Differential input paired with +IN; supports hysteresis configuration via external feedback |
| 4 (OUT) | Push-pull output | Active-high/low drive capable of sourcing/sinking ≥4 mA; no pull-up resistor needed |
| 5 (SD) | Shutdown control (active low) | Logic-compatible enable/disable; high-impedance input requiring defined logic level - must not float |
| 6 (V+) | Positive power terminal | Accepts 2.7–5.25 V; internal ESD protection rated to 5.5 V allows 5-V logic control even at 3-V V+ |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3601DBVR | Higher speed (4.5 ns propagation delay), but 1.5 mV max VOS and no shutdown pin; 5-pin SOT-23 package | Better suited for RF envelope detection or laser pulse timing; unsuitable for low-power shutdown scenarios | Select TLV3601DBVR only when nanosecond response dominates over precision and power savings |
| MAX9060ASA+ | 0.5 mV max VOS, 200 ns propagation delay, integrated hysteresis (20 mV), 8-pin SOIC only | Reduces external component count in window/detector designs but lacks shutdown and SOT-23 option | Choose MAX9060ASA+ when fixed hysteresis simplifies layout and SOIC footprint is acceptable |

FAQ
What is the maximum supply voltage rating for LMV761MFX/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV761MFX/NOPB is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 2.7 V to 5.25 V, ensuring full specification compliance across −40°C to +125°C ambient temperature. Exceeding 5.25 V may degrade VOS stability and increase supply current unpredictably.
Does LMV761MFX/NOPB require an external pull-up resistor on its output?
No, LMV761MFX/NOPB does not require an external pull-up resistor because it features a push-pull output stage. The output actively drives high (up to V+ − 0.1 V) and low (down to 120 mV max at −4 mA sink), enabling direct connection to CMOS or TTL inputs without passive components - reducing BOM count and board area.
Can the shutdown pin (SD) of LMV761MFX/NOPB be driven by 5-V logic while V+ is at 3.3 V?
Yes, the SD pin of LMV761MFX/NOPB accepts up to 5.5 V regardless of V+ voltage. This allows 5-V microcontroller GPIO or logic gates to control shutdown even when the comparator operates from a lower 2.7–3.3 V supply - a key advantage for mixed-voltage system design and simplifies level-shifting requirements.
What is the input common-mode voltage range for LMV761MFX/NOPB at 5 V supply?
At 5 V supply, the input common-mode voltage range for LMV761MFX/NOPB is −0.3 V to 3.8 V, referenced to V− (GND). This rail-to-rail input capability enables direct sensing of ground-referenced signals and compatibility with most single-supply sensor outputs, while maintaining >50 dB CMRR across the full range.
How does LMV761MFX/NOPB perform in terms of power supply rejection?
LMV761MFX/NOPB delivers 110 dB typical PSRR across 2.7–5 V supply range, meaning a 1 V ripple on V+ induces only ~3 µV error at the input stage. This high PSRR ensures stable threshold detection in electrically noisy environments such as motor controllers or switch-mode power supply feedback paths without additional filtering.
