LMC6772AIM/NOPB

Overview

The LMC6772AIM/NOPB is a dual micro-power rail-to-rail input CMOS comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and consumes only 20 µA of operating current. The device features an open-drain output type and is housed in an 8-SOIC package. Key electrical specifications include a maximum input offset voltage of 8 mV, a typical common-mode rejection ratio (CMRR) of 75 dB, and a typical power supply rejection ratio (PSRR) of 80 dB. It supports a single or dual supply configuration.

Feature Summary

• Dual micro-power operation with rail-to-rail input capability for extended signal range utilization
• Open-drain output structure enabling flexible interfacing with various logic families
• High common-mode rejection and power supply rejection ratios for stable performance under varying conditions

Applications

• Battery-powered portable instrumentation systems requiring low quiescent current
• Threshold detection circuits in consumer electronics
• Signal conditioning stages in industrial control modules

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and electrical tolerances. Ensure that the procurement channel provides authentic components with traceable manufacturing dates. Cross-reference the RoHS compliance status with current regulatory requirements for the target market. Confirm that the packaging format matches the intended automated assembly process.

Selection Notes

Select this component when designing circuits that demand minimal static power consumption while maintaining accurate voltage comparison capabilities. The rail-to-rail input feature makes it suitable for applications where input signals swing close to the supply rails. Consider the open-drain output requirement for pull-up resistor selection in the final circuit design. Evaluate the thermal performance within the specified operating temperature range during system integration.

Part Context

This part belongs to the LMC6772 series of analog comparators from Texas Instruments. It is designed as a low-cost, low-power alternative to traditional bipolar comparators. The device integrates two independent comparators into a single compact package, optimizing board space for dense electronic designs. It serves as a fundamental building block for basic voltage monitoring and switching applications.

Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitute part numbers. Ensure that any alternative component maintains identical pin configurations and electrical characteristics to avoid redesigning the existing circuit layout.
