LMC6772AIMX

Overview

The LMC6772AIMX is a dual low-power comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates on a single or dual supply voltage ranging from 2.7V to 15V (±1.35V to ±7.5V). Key electrical specifications include a maximum input offset voltage of 5mV at 5V, a typical input bias current of 0.04pA, and a maximum propagation delay of 10µs. The device features open-drain outputs and supports a typical common-mode rejection ratio of 75dB and power supply rejection ratio of 80dB. It functions within a temperature range of -40°C to 85°C.

Feature Summary

• Dual-channel architecture providing two independent comparison circuits in a compact package.
• Ultra-low quiescent current consumption suitable for battery-powered applications.
• Rail-to-rail input capability allowing signal processing near supply rails.
• Open-drain output configuration enabling flexible interfacing with various logic families.

Applications

• Battery-operated portable devices requiring minimal power draw
• Threshold detection circuits in industrial monitoring systems
• Signal conditioning interfaces for microcontroller inputs

Procurement Notes

Verify the specific suffix 'MX' against the manufacturer's official datasheet to confirm the tape-and-reel packaging variant. Ensure the component meets RoHS3 compliance requirements if mandated by your assembly standards. Cross-reference the ordering part number with Texas Instruments documentation to validate the exact pinout and thermal characteristics for your PCB layout.

Selection Notes

Select this component when dual comparators are needed with strict power constraints. The rail-to-rail input feature is critical for applications where signals swing close to ground or the positive supply. The open-drain output requires external pull-up resistors; ensure the chosen resistor value aligns with the desired switching speed and load capacitance for your specific circuit design.

Part Context

This device belongs to the LMC6772 family of low-power CMOS comparators. It serves as a general-purpose solution for analog signal comparison tasks. The SOIC-8 package offers a balance between pin count and board space efficiency. It is designed to replace older bipolar comparator technologies where lower power consumption and wider input voltage ranges are required.

Replacement Considerations

Consult the Texas Instruments LMC6772 datasheet for direct pin-compatible alternatives within the same product line. Verify that any substitute maintains the 2.7V minimum operating voltage and open-drain output structure to ensure circuit compatibility without redesigning the pull-up network.
