LMC6762AIM

Overview

The LMC6762AIM is a dual micro-power rail-to-rail input CMOS comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7V to 15V, or dual supplies of ±1.35V to ±7.5V. The device features push-pull outputs and draws a maximum static current of 20µA. Key electrical specifications include a maximum propagation delay of 10µs, an input offset voltage of up to 15mV at 5V, and a maximum input bias current of 0.04pA at 5V. Common mode rejection ratio (CMRR) is typically 75dB, while power supply rejection ratio (PSRR) is typically 80dB. It supports a typical output current of 30mA and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Dual micro-power CMOS architecture with rail-to-rail input capability for extended signal range utilization.
• Push-pull output stage design enabling direct interfacing with digital logic families without additional pull-up components.
• Low quiescent current consumption optimized for battery-powered and energy-efficient applications.

Applications

• Battery-operated instrumentation systems requiring low power dissipation
• Threshold detection circuits in portable electronic devices
• Signal conditioning interfaces for microcontroller analog inputs

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required operating conditions. Confirm that the component status aligns with long-term availability requirements, as certain variants may be subject to discontinuation notices. Cross-reference the package dimensions and pinout with PCB layout specifications before finalizing procurement decisions.

Selection Notes

Select this component when dual-channel comparison is needed with minimal power draw and full input voltage swing coverage. Ensure the application does not require faster response times than the specified 10µs propagation delay. Verify that the 30mA output drive capability meets the load requirements of the connected circuitry without exceeding thermal limits.
