LMV761MFX/NOPB

Overview

The LMV761MFX/NOPB is a precision analog comparator manufactured by Texas Instruments, housed in an SOT-23-6 surface-mount 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. The device features a push-pull output stage and differential inputs. Key electrical specifications include a maximum input offset voltage of 1 mV, input bias current of 50 pA, and input offset current of 5 pA. Common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) are both rated at 80 dB. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Precision performance characterized by low input offset voltage and minimal input bias currents for accurate signal comparison.
• Push-pull output architecture provides defined logic levels without requiring external pull-up resistors.
• Operates effectively across a wide industrial temperature range while maintaining stable electrical characteristics.

Applications

• Battery-powered systems requiring low quiescent current consumption
• Threshold detection circuits for voltage monitoring
• Signal conditioning interfaces in portable electronic devices

Procurement Notes

Verify the specific suffix MFX indicates the reel packaging format when ordering. Confirm that the NOPB designation ensures compliance with RoHS standards and absence of hazardous substances. Cross-reference the manufacturer part number with distributor catalogs to ensure availability of the correct tape-and-reel quantity. Check for any recent product change notices regarding pinout or electrical parameter updates.

Selection Notes

Select this component when a single-channel comparator with high precision and low power consumption is required. The SOT-23-6 package suits space-constrained designs. Ensure the application voltage remains within the 2.7 V to 5.25 V range. Consider the push-pull output capability if driving subsequent digital logic directly without additional components.

Part Context

This device belongs to the LMV761 series of low-voltage precision comparators from Texas Instruments. It is designed for applications where accuracy and power efficiency are critical. The series offers various package options, including SOIC and MSOP, but this specific variant utilizes the compact SOT-23-6 form factor suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult official substitution guides for equivalent parts within the same family or alternative manufacturers offering similar precision comparator specifications. Verify pin compatibility and electrical parameter alignment before replacing the component in existing designs.
