Product details
Overview
LMV761MA/NOPB from Texas Instruments is a single, low-voltage precision comparator with push-pull output and active-low shutdown pin, designed for 2.7-V to 5.25-V single-supply operation. It delivers 0.2 mV typical input offset voltage, 120 ns propagation delay at 50 mV overdrive, 300 µA supply current, and operates across −40°C to +125°C - enabling high-accuracy threshold detection in portable battery-powered systems.
For engineers reviewing the LMV761MA/NOPB datasheet, LMV761MA/NOPB pinout, LMV761MA/NOPB application, or LMV761MA/NOPB equivalent, key selection criteria include shutdown-enabled ultra-low quiescent current (20 nA in 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 guaranteed 1 mV max VOS over temperature.
Technical Context
The LMV761MA/NOPB implements a CMOS-input, push-pull-output architecture optimized for low-noise, low-offset decision-making in single-supply environments. Its input stage achieves 0.2 pA typical bias current and 100 dB CMRR, while the output drives ±4 mA with VOH = VCC − 0.1 V and VOL = 250 mV at 5 V supply.
Shutdown functionality is implemented via an active-low SD pin with logic thresholds proportional to VCC, supporting mixed-voltage control (e.g., 5-V logic driving 2.7-V VCC). In shutdown mode, output enters high-impedance state and supply current drops to 20 nA - critical for intermittent-sensing applications.
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 logic rails without level-shifting. |
| Input Offset Voltage (max) | 1 mV over −40°C to +125°C - ensures stable trip-point accuracy in automotive and industrial ambient conditions. |
| Propagation Delay | 120 ns at 50 mV overdrive (5 V supply) - enables reliable high-speed edge detection in sampling circuits and zero-crossing detectors. |
| Supply Current (typ) | 300 µA at 5 V - balances speed and power for always-on sensing nodes in battery-constrained devices. |
| Shutdown Current | 20 nA - reduces system standby power by >99.9% versus active mode, extending battery life in duty-cycled applications. |
| CMRR / PSRR | 100 dB / 110 dB - rejects supply and common-mode noise in noisy embedded environments like motor controls and power supplies. |
| Output Type | Push-pull - eliminates need for external pull-up resistor, simplifying PCB layout and reducing BOM count. |
Pinout & Package
LMV761MA/NOPB is packaged in an 8-pin SOIC (D package) with 4.90 mm × 3.91 mm body size. Pin 1 is N/C (not internally connected); pins 2–8 are functionally assigned as specified below.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 N/C | No Connect | Unbonded die pad - must remain floating or grounded per layout guidelines; no electrical function. |
| 2 −IN | Inverting Input | Differential input node accepting reference or inverted signal; supports common-mode range down to −0.3 V. |
| 3 +IN | Noninverting Input | Differential input node accepting sensed signal; matched input impedance and bias current to −IN. |
| 4 V− | Negative Power Terminal | Ground reference for single-supply operation; connects to system GND or negative rail in split-supply configs. |
| 5 SD | Shutdown Control (active low) | High-impedance digital input; pulling low disables comparator and forces output to high-Z, reducing ICC to 20 nA. |
| 6 OUT | Push-Pull Output | CMOS-compatible digital output sourcing/sinking up to ±4 mA; no external pull-up required. |
| 7 V+ | Positive Power Terminal | Supplies internal circuitry; requires local 0.1 µF ceramic decoupling to minimize switching transients. |
| 8 N/C | No Connect | Unbonded die pad - electrically isolated; may be tied to GND for thermal or mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 0.2 pA typical - enables use of megaohm-level resistive dividers and femtofarad-level timing capacitors without error drift. |
| Guaranteed 1-mV VOS over temp | Ensures consistent threshold accuracy across automotive and industrial temperature ranges without calibration. |
| Integrated shutdown mode | Reduces supply current to 20 nA and places output in high-impedance state - ideal for microcontroller-gated sensing intervals. |
| Rail-to-rail input common-mode range | Operates with inputs as low as −0.3 V and as high as VCC − 1.3 V - supports direct interfacing to sensors and DACs near supply rails. |
| Push-pull output stage | Eliminates external pull-up resistor, saving board space and preventing rise-time degradation in high-capacitance loads. |

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 active), no shutdown pin, 360 ns propagation delay, 2.5-V min supply. | Better for ultra-low-power always-on wake-up circuits; unsuitable where fast response or shutdown control is required. | Select TLV3691IDBVR only when <200 nA active current dominates design priority and 360 ns delay is acceptable. |
| MAX9060ASA+ | Higher speed (45 ns), rail-to-rail output, no shutdown, 1.8-V min supply, 1.5 mV max VOS. | Preferred for high-frequency sampling where speed outweighs offset precision; lacks shutdown for power-gated systems. | Choose MAX9060ASA+ when propagation delay <50 ns is mandatory and 1.5 mV VOS meets system accuracy requirements. |
Compared with TLV3691IDBVR and MAX9060ASA+, LMV761MA/NOPB uniquely balances sub-millivolt offset accuracy, 120 ns speed, and integrated shutdown - making it optimal for battery-powered instrumentation requiring both precision and adaptive power management.

FAQ
What is the maximum supply voltage rating for LMV761MA/NOPB?
The absolute maximum supply voltage (V+ – V−) for LMV761MA/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 including 1 mV max input offset voltage and 120 ns propagation delay performance.
Does LMV761MA/NOPB require an external pull-up resistor on its output?
No, LMV761MA/NOPB does not require an external pull-up resistor because it features a push-pull output stage capable of actively sourcing and sinking current. This eliminates external components, reduces board area, and avoids rise-time limitations associated with RC time constants in open-drain configurations.
How does the shutdown pin (SD) function on LMV761MA/NOPB?
The SD pin on LMV761MA/NOPB is active-low: driving it to GND disables the comparator, places the output in high-impedance state, and reduces supply current to 20 nA. The pin accepts logic voltages up to 5.5 V independent of VCC, allowing 5-V controllers to manage lower-voltage LMV761MA/NOPB instances safely.
What is the input common-mode voltage range for LMV761MA/NOPB at 5-V supply?
At 5-V supply, the input common-mode voltage range for LMV761MA/NOPB is −0.3 V to 3.8 V (VCC − 1.3 V), with CMRR > 50 dB across that span. This rail-to-rail capability enables direct interface with sensors, DACs, and other circuitry operating near ground or supply rails without level-shifting networks.
Is LMV761MA/NOPB qualified for automotive applications?
LMV761MA/NOPB itself is not AEC-Q100 qualified; however, the pin-compatible LMV762Q-Q1 dual variant is certified for automotive Grade 1 (−40°C to +125°C). LMV761MA/NOPB shares identical electrical specifications and thermal performance but lacks formal automotive qualification documentation and stress-test reporting.
