LMV761MAX

Overview

The LMV761MAX is a precision analog comparator from Texas Instruments, housed in an 8-pin SOIC package. It operates on a single supply voltage ranging from 2.7 V to 5.25 V with a typical quiescent current of 271 uA. Key electrical characteristics include a maximum input offset voltage of 1 mV and low input bias current of 50 pA. The device features a push-pull output stage and supports differential inputs. It offers high common-mode rejection ratio (CMRR) of 80 dB and power supply rejection ratio (PSRR) of 80 dB. The component functions reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Precision performance with low input offset voltage for accurate signal threshold detection
• Low power consumption suitable for battery-operated applications
• Push-pull output stage providing strong drive capability without requiring external pull-up resistors
• Wide operating temperature range ensuring stability in harsh environments

Applications

• Battery-powered monitoring systems
• Threshold detection circuits
• Over-voltage protection schemes
• Temperature sensing interfaces

Procurement Notes

Verify the specific suffix 'MAX' against the manufacturer's official datasheet to confirm pinout and package dimensions match your PCB footprint requirements. Ensure the ordering part number includes the correct tape-and-reel or tube packaging designation if volume procurement is planned. Cross-reference the RoHS compliance status with the latest environmental declaration documents provided by Texas Instruments before finalizing purchase orders.

Selection Notes

Select this component when precise voltage comparison is required with minimal power draw. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider the push-pull output if direct logic interfacing is needed without additional components. Evaluate the 1 mV offset voltage specification against your application's accuracy requirements to ensure sufficient margin for reliable switching operations under varying temperature conditions.

Part Context

The LMV761MAX belongs to the LMV761 series of low-voltage precision comparators designed by Texas Instruments. This series focuses on delivering op-amp-like precision in a comparator form factor. The MAX suffix typically denotes a specific package variant, often associated with industrial temperature ranges or specific mounting styles within the company's product lineup. It serves as a drop-in replacement for older precision comparator designs where power efficiency is critical.

Replacement Considerations

Consult the official cross-reference guide for verified substitutes such as the LMV761MFX/NOPB for different packaging needs. Ensure any alternative maintains the same push-pull output configuration and voltage range compatibility.
