Product details
Overview
LMV761MAX/NOPB from Texas Instruments is a single, low-voltage precision comparator with push-pull output and active-low shutdown pin, operating from 2.7 V to 5.25 V supply. It delivers 120 ns propagation delay (50 mV overdrive), 0.2 mV typical input offset voltage, 0.2 pA input bias current, and supports −40°C to +125°C ambient operation - ideal for battery-powered threshold detection in portable instrumentation.
For engineers reviewing the LMV761MAX/NOPB datasheet, LMV761MAX/NOPB pinout, LMV761MAX/NOPB application, or LMV761MAX/NOPB equivalent, key selection criteria include shutdown-enabled ultra-low quiescent current (275 μA active, 20 nA shutdown), rail-to-rail input common-mode range (−0.3 V to VCC − 1.3 V), push-pull output eliminating external pull-up resistors, and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV761MAX/NOPB implements a CMOS-input, push-pull-output architecture optimized for single-supply precision comparison. Its internal design enables near-zero input bias current (0.2 pA typ) and high CMRR (100 dB) and PSRR (110 dB), ensuring stable decision thresholds under varying supply and common-mode conditions.
Shutdown functionality is implemented via an active-low SD pin referenced to ground (not VCC), allowing independent 5-V logic control even at 2.7-V VCC. In shutdown mode, output enters high-impedance state and supply current drops to 20 nA - critical for intermittent-sensing applications like wake-on-event sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.25 V - supports direct connection to Li-ion cell (3.0–4.2 V) or 3.3 V/5 V rails without regulation. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures ≤1 mV decision error across full automotive temperature range. |
| Propagation Delay | 120 ns at 50 mV overdrive - enables reliable sampling of signals up to ~4 MHz edge rate in timing-critical circuits. |
| Supply Current (active) | 275 μA typ at 2.7 V - allows >1-year battery life in coin-cell-powered wake-up comparators with 1 Hz polling. |
| Shutdown Supply Current | 20 nA max - reduces standby power by >13,000× versus active mode, enabling multi-year shelf life in IoT endpoints. |
| Input Bias Current | 0.2 pA typ - permits use of >10 MΩ feedback/resistor networks without offset drift or signal loading errors. |
| Output Type | Push-pull (no external pull-up required) - simplifies BOM, eliminates rise-time uncertainty, and supports direct TTL/CMOS interfacing. |
Pinout & Package
LMV761MAX/NOPB is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size. Pin 1 is +IN; pin 2 is −IN; pin 3 is V−; pin 4 is SD (active-low shutdown); pin 5 is OUT; pin 6 is V+; pins 1 and 8 are no-connect.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (Pin 1) | Noninverting input | Accepts analog input up to V+ − 1.3 V; high-impedance node (0.2 pA bias) enables high-Z sensor interfacing. |
| −IN (Pin 2) | Inverting input | Reference input node; matched to +IN for <1 mV offset over temp; supports hysteresis feedback networks. |
| V− (Pin 3) | Negative power terminal | Ground reference for single-supply operation; must be connected directly to system GND plane. |
| SD (Pin 4) | Shutdown control (active low) | Drives low to disable comparator and reduce ICC to 20 nA; logic threshold scales with V+; must not float. |
| OUT (Pin 5) | Digital output | Push-pull CMOS output sourcing/sinking ≥2 mA; swings from V− to V+ − 0.1 V (at 2 mA load). |
| V+ (Pin 6) | Positive power terminal | Supplies internal circuitry; requires local 0.1 µF ceramic decoupling to GND per layout guidelines. |
| N/C (Pin 7) | No connect | Internally unconnected; may be left floating or tied to GND for mechanical stability - no electrical function. |
| N/C (Pin 8) | No connect | Internally unconnected; same as Pin 7 - no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| Precision offset performance | 0.2 mV typical / 1 mV max over −40°C to +125°C - enables accurate voltage monitoring in automotive and industrial sensors. |
| Ultra-low input bias current | 0.2 pA typical - eliminates resistor-matching requirements and enables high-impedance RC timing networks (e.g., slow ramp generators). |
| Integrated shutdown | 20 nA shutdown current with active-low SD pin - supports duty-cycled sensing architectures without external enable circuitry. |
| Push-pull output stage | No external pull-up needed; 2 mA drive capability into 5.1 kΩ load - reduces component count and improves rise/fall time consistency. |
| High PSRR and CMRR | 110 dB PSRR / 100 dB CMRR - maintains threshold accuracy despite supply ripple or common-mode noise on sensor inputs. |
Applications
| Portable Power Monitoring | Automotive Battery Supervision |

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 typ), no shutdown pin, 350 ns propagation delay, 1.8–5.5 V range. | Better for ultra-low-power always-on monitoring; unsuitable where fast response or shutdown control is required. | Select TLV3691IDBVR only when sub-μA quiescent current dominates over speed and controllability needs. |
| LMV331M5X/NOPB | Higher offset (7 mV max), no shutdown, 200 ns delay, 2.7–5.5 V, SOT-23-5 package (no SD pin). | Cost-optimized alternative for non-critical thresholds; lacks precision and power-gating capability. | Choose LMV331M5X/NOPB only for cost-sensitive consumer applications where 1 mV offset and shutdown are unnecessary. |
Compared with TLV3691IDBVR and LMV331M5X/NOPB, LMV761MAX/NOPB uniquely balances nanosecond-speed response (120 ns), precision offset (1 mV max), and hardware-controllable shutdown (20 nA) in a single SOIC-8 package - making it the only option for battery-powered industrial sensors requiring both accuracy and intelligent power cycling.

FAQ
What is the maximum operating supply voltage for LMV761MAX/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV761MAX/NOPB is 5.5 V. The recommended operating range is 2.7 V to 5.25 V. Exceeding 5.5 V risks permanent damage per Absolute Maximum Ratings. Operation at 5.25 V is fully supported across −40°C to +125°C and maintains all specified electrical characteristics including 120 ns propagation delay and 1 mV max offset voltage for LMV761MAX/NOPB.
Does LMV761MAX/NOPB require an external pull-up resistor on its output?
No, LMV761MAX/NOPB does not require an external pull-up resistor because it features a push-pull output stage. The output actively drives high (to V+ − 0.1 V at 2 mA) and low (to V− + 250 mV at −2 mA), enabling direct interfacing with CMOS/TTL logic without additional components. This eliminates rise-time uncertainty and reduces BOM count - a confirmed design feature of LMV761MAX/NOPB per its functional description and typical application schematics.
How does the shutdown pin (SD) function on LMV761MAX/NOPB?
The SD pin on LMV761MAX/NOPB is active-low: driving it low disables the comparator, places the output in high-impedance state, and reduces supply current to 20 nA max. SD is referenced to ground (not V+), accepts up to 5.5 V logic, and has V+–proportional thresholds. It must never be left floating - an unconnected SD causes undefined output behavior. This shutdown behavior is explicitly verified for LMV761MAX/NOPB in the Device Functional Modes section of the official datasheet.
What is the input common-mode voltage range for LMV761MAX/NOPB at 5 V supply?
At V+ = 5 V, the input common-mode voltage range for LMV761MAX/NOPB is −0.3 V to 3.8 V (V+ − 1.3 V), specified for CMRR > 50 dB. This rail-to-rail capable input allows direct sensing of signals down to 300 mV below ground (e.g., current-sense shunts) and up to 1.2 V below V+, supporting wide dynamic range in single-supply systems - a confirmed parameter in the 5-V Electrical Characteristics table for LMV761MAX/NOPB.
Is LMV761MAX/NOPB qualified for automotive applications?
No, LMV761MAX/NOPB is not AEC-Q100 qualified. Only the LMV762Q-Q1 variant in the same family carries automotive qualification (Grade 1, −40°C to +125°C, HBM ±2000 V). LMV761MAX/NOPB is rated for industrial temperature range (−40°C to +125°C) but lacks automotive-specific stress testing, failure analysis, and documentation required for automotive use. For automotive designs, TI explicitly positions LMV762Q-Q1 - not LMV761MAX/NOPB - as the qualified solution.
