LMV761MF

Overview

The LMV761MF is a low-voltage, precision analog comparator manufactured by Texas Instruments. It features a push-pull output stage and operates within a supply voltage range of 2.7 V to 5.25 V. The device draws a typical operating current of 271 uA. Key electrical specifications include an input offset voltage of 1 mV, an input bias current of 50 pA, and an input offset current of 5 pA. It provides a common-mode rejection ratio (CMRR) of 80 dB and a power supply rejection ratio (PSRR) of 80 dB. The component is housed in a SOT-23-6 package and supports a differential input type.

Feature Summary

• Low-voltage operation capability with a wide supply range from 2.7 V to 5.25 V
• Precision performance characterized by low input offset voltage and minimal bias currents
• Push-pull output architecture for direct interfacing with digital logic circuits

Applications

• Battery-powered systems requiring low quiescent current
• Threshold detection and level sensing applications
• Signal conditioning in portable electronic devices

Procurement Notes

Verify the specific suffix 'MF' against the official Texas Instruments datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm RoHS compliance status through the manufacturer's documentation before integration into the design.

Selection Notes

Select this component when a single-channel precision comparator is needed with low power consumption and fast response times. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 271 uA supply current for battery life calculations and verify that the 1 mV offset voltage meets the accuracy requirements of the application.

Part Context

The LMV761MF belongs to the LMV76x family of low-voltage precision comparators. This series is designed for applications where power efficiency and accuracy are critical. The device complements other components in Texas Instruments' analog signal chain portfolio, offering a compact solution for voltage monitoring and switching tasks in space-constrained designs.

Replacement Considerations

Check for pin-compatible alternatives such as the LMV761MFX or LMV761MX if different packaging options are required. Verify that substitute parts maintain the same 2.7 V to 5.25 V supply range and push-pull output characteristics to ensure functional equivalence.
