LMV761MF/NOPB Overview
A comparator is an analog integrated circuit that compares two input voltages and changes its output state when the differential input crosses a defined threshold. Unlike an operational amplifier, a comparator is optimized for saturated digital-style output states rather than linear amplification. The LMV761 belongs to the broader semiconductor hierarchy of analog ICs, comparator circuits, and low-voltage precision signal-conditioning components.
The LMV761MF/NOPB provides a single comparator channel with rail-to-rail input capability, push-pull output, and a shutdown pin. Its 120 ns propagation delay supports fast decision paths, while its low supply current makes it suitable for portable and low-power equipment. The push-pull output avoids the external pull-up resistor normally required by open-collector comparators, simplifying PCB layout and reducing system component count.
This comparator is particularly useful when a system must convert an analog measurement into a logic-level decision without adding substantial propagation delay. Its 2.7 V minimum supply voltage supports low-voltage digital and embedded systems, while operation up to 5 V provides compatibility with conventional low-voltage rails. The SOT-23-6 package supports compact placement, although designers should account for the small thermal footprint and exposed pad limitations of the package family.
Typical applications include sensor threshold detection, battery and power-supply monitoring, signal crossing detection, window-comparison circuits, industrial control logic, portable instrumentation, and low-voltage embedded systems. The shutdown function can reduce supply current when the comparator is not needed, helping conserve power in always-on equipment.
For reliable operation, connect the supply and ground pins according to the manufacturer datasheet, place bypass capacitance close to the device, and treat unused input pins carefully. Input common-mode range, output drive capability, and shutdown logic should be verified against the system requirements before layout release.

Typical Applications
LMV761MF/NOPB is suitable for 6 applications: Battery-Powered Sensor Threshold Detection, Low-Voltage Power-Supply Monitoring, Portable Instrument Signal Conditioning, Embedded System Threshold Logic, Battery Charger and Protection Control, Industrial Control and Sensor Interfacing.
Battery-Powered Sensor Threshold Detection
The LMV761MF/NOPB is well suited to comparing a sensor-derived voltage against a reference threshold because it combines rail-to-rail input capability with a 120 ns propagation delay and 2.75 uA specified supply current. In a portable sensing system, the comparator can generate a clean digital state when the sensor signal crosses its alarm or operating threshold. Its shutdown pin can reduce consumption when the sensor path is inactive. The designer should verify the actual input common-mode limits and output load from the current TI datasheet before finalizing the circuit.
Recommended
Low-Voltage Power-Supply Monitoring
Use the LMV761MF/NOPB to monitor a 2.7 V to 5 V rail or another low-voltage node when a fast hardware decision is needed. Its 120 ns response time allows a supervisor-like circuit to react quickly when a regulated rail crosses a programmed threshold, while the push-pull output can drive downstream logic without an open-collector pull-up resistor. The shutdown function can help reduce power in systems that periodically perform rail checks. A complete design should account for input filtering, threshold accuracy, and the comparator's behavior during startup and supply transients.
Recommended
Portable Instrument Signal Conditioning
The LMV761MF/NOPB can convert a slowly changing analog measurement into a fast logic decision in portable test and measurement equipment. Its low-voltage operation supports compact battery-powered instruments, while the 120 ns response time helps minimize delay in threshold-based measurement paths. The push-pull output simplifies interfacing to digital control logic, and shutdown can be asserted during inactive periods. For best results, keep the comparison node short, provide local supply bypassing, and verify offset and noise specifications required by the measurement accuracy budget.
Recommended
Embedded System Threshold Logic
The LMV761MF/NOPB is appropriate for embedded systems that need a hardware-level decision alongside firmware monitoring. A comparator can assert an interrupt, enable a load switch, or initiate a safe state when a voltage or temperature-derived signal crosses a limit. Its 2.7 V to 5 V supply range aligns with many embedded rails, and the 120 ns delay is useful for fast fault detection. Designers should define input polarity and hysteresis carefully to prevent chatter, and should confirm that the output voltage levels meet the connected controller's logic requirements.
Recommended
Battery Charger and Protection Control
The LMV761MF/NOPB can support fast threshold decisions in battery charger and protection circuits by monitoring a divided battery or supply voltage against a reference. Its low specified supply current and shutdown capability help fit low-power systems. The push-pull output can provide a direct logic signal to a controller or discrete gate-control stage, while the 120 ns response is useful for rapid overvoltage or undervoltage detection. Actual protection performance depends on the reference accuracy, divider design, filtering, and the exact input range; these must be validated against the battery chemistry and safety requirements.
Recommended
Industrial Control and Sensor Interfacing
The LMV761MF/NOPB is useful in industrial control logic for converting a sensor or condition signal into a decisive digital state. Its low-voltage operation makes it suitable for embedded control boards, while the push-pull output simplifies connection to digital inputs. The comparator can be used for over-limit, under-limit, or signal-crossing detection, provided the input signal stays within the supported common-mode range. In industrial environments, filtering and layout are important because fast comparators can respond to switching noise on long PCB traces; add appropriate protection and validate timing under worst-case conditions.

Key Differentiators

- Shutdown support (vs LMV761MFX)
- Single-channel footprint with push-pull output (vs LMV762MF/NOPB)
Design Notes
Keep the supply bypass capacitor physically close to the device supply and ground pins. Because the LMV761 is a fast comparator, long supply and ground traces can increase susceptibility to switching noise and create output instability near the decision threshold. Use a short, low-impedance ground return and place input filtering components close to the relevant input pins rather than at a distant connector.
Use hysteresis or controlled filtering when the compared signal can cross the threshold slowly. Slow input transitions combined with comparator noise can cause output chatter, even when the nominal 120 ns propagation delay is much faster than the system timing requirement. Validate the threshold circuit across temperature, supply tolerance, and worst-case input slew rate before production release.
The verified 2.7 V to 5 V supply range allows operation from low-voltage rails, but the comparator output must remain compatible with the connected logic family. Confirm output voltage levels under the intended load and ensure that the shutdown pin is never left floating. If the supply can start slowly or ramp through an undefined state, add external control or reset logic to prevent unintended decisions.
