Overview
The LMV761MA/NOPB is a single-channel precision analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 2.7 V to 5.25 V and draws a typical operating current of 271 uA. Key electrical specifications include a maximum input offset voltage (Vos) of 1 mV, an input bias current (Ib) of 50 pA, and an input offset current (Ios) of 5 pA. The device features a push-pull output type and supports differential inputs. It provides a common-mode rejection ratio (CMRR) of 80 dB and a power supply rejection ratio (PSRR) of 80 dB. The component functions reliably across an extended 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 capable of driving digital logic interfaces directly
Applications
- Battery-powered monitoring systems requiring low quiescent current
- Threshold detection circuits in consumer electronics
- Signal conditioning stages in industrial instrumentation
Procurement Notes
Verify the specific ordering suffix matches the required package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component aligns with the intended thermal and electrical operating conditions defined in the datasheet. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and availability.
Selection Notes
Select this component when a single-channel comparator with high precision and low power consumption is required. The LMV761MA/NOPB is appropriate for designs needing rail-to-rail input capabilities and push-pull outputs. Consider the SOIC-8 package constraints for PCB layout. Evaluate the 1 mV offset voltage specification against the application's accuracy requirements to ensure sufficient margin for noise immunity.
Part Context
This device belongs to the LMV761 series of low-voltage precision comparators. It is designed to offer improved performance over standard comparators while maintaining low power usage. The family includes variants with different packaging options, such as the MFX version in SOT-23-6. The LMV761MA/NOPB specifically utilizes the tube packaging format, distinguishing it from tape-and-reel alternatives within the same functional family.
Replacement Considerations
Direct pin-compatible substitutes within the same series include other LMV761 variants with different packaging, such as LMV761MFX/NOPB. Verify that any replacement maintains the same SOIC-8 footprint and electrical characteristics if board space is constrained.
