Overview
The LMV761MFX is a single-channel, low-voltage precision 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. Key electrical parameters include a maximum input offset voltage of 1 mV, an input bias current of 50 pA, and a quiescent current of 271 µA. The device offers a common-mode rejection ratio (CMRR) of 80 dB and a power supply rejection ratio (PSRR) of 80 dB. It is housed in a SOT-23-6 package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Precision performance with low input offset voltage for accurate signal detection
- Push-pull output driver capable of sourcing and sinking current without external pull-up resistors
- Low power consumption suitable for battery-operated applications
- Wide common-mode input voltage range extending beyond the supply rails
Applications
- Battery-powered monitoring systems
- Threshold detection circuits
- Over-voltage protection schemes
- Temperature sensing interfaces
Procurement Notes
Verify the component marking and date code against the manufacturer's latest datasheet revision history. Confirm that the SOT-23-6 package dimensions match your PCB footprint requirements. Ensure the supply voltage applied does not exceed the absolute maximum rating of 5.25 V to prevent device damage. Check for RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a single comparator with rail-to-rail input capability and a robust push-pull output is required. It is suitable for designs where minimizing external components is critical due to the integrated output stage. Consider the 1 mV offset voltage specification for applications requiring high accuracy in low-voltage differential measurements.
