Overview
The LMV761MA is a single-channel precision analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.25 V and consumes 271 uA of operating current. The device features a push-pull output type and differential input configuration. Key electrical specifications include an input offset voltage (Vos) of 1 mV, input bias current (Ib) of 50 pA, and input offset current (Ios) of 5 pA. Common-mode rejection ratio (CMRR) is 80 dB, and power supply rejection ratio (PSRR) is 80 dB. It functions reliably across a temperature range from -40 C to +125 C.
Feature Summary
- Precision performance with low input offset voltage for accurate signal comparison
- Low power consumption suitable for battery-operated applications
- Push-pull output stage providing strong drive capability
Applications
- Battery-powered sensing systems
- Threshold detection circuits
- Signal conditioning modules
Procurement Notes
Verify the specific suffix MA against the official datasheet to confirm package type and tape/reel or tube packaging details. Ensure the ordering part number matches the required temperature grade and RoHS compliance status. Cross-reference the manufacturer's latest documentation for any pinout or functional updates before finalizing procurement orders.
Selection Notes
Select this component when a single-channel comparator with high precision and low quiescent current is required. The 1 mV offset voltage makes it suitable for applications demanding accurate threshold detection. Consider the SOIC-8 package constraints and the 2.7 V minimum supply voltage during circuit design. Verify that the push-pull output meets the load requirements of the downstream interface.
Part Context
The LMV761MA belongs to the LMV761 series of low-voltage precision comparators from Texas Instruments. This series is designed for applications requiring high accuracy in low-power environments. The device integrates a single comparator channel optimized for performance in portable and industrial electronics where power efficiency and signal integrity are critical.
Replacement Considerations
Consult the official datasheet for direct pin-to-pin replacements within the same family. Verify compatibility regarding supply voltage ranges and output drive capabilities when substituting with other precision comparers.
