LMC6772BIMX

Overview

The LMC6772BIMX is a dual low-power analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 15 V and draws an operating supply current of 20 uA. The device features open-drain outputs, a response time of 4 us, and an input bias current of 0.04 pA. Key electrical parameters include an input offset voltage (Vos) of 18 mV, a common-mode rejection ratio (CMRR) of 75 dB, and a power supply rejection ratio (PSRR) of 80 dB. It supports rail-to-rail inputs and functions across a temperature range of -40 C to +85 C in an SOIC-8 package.

Feature Summary

• Dual-channel general-purpose analog comparator design
• Ultra-low power consumption with 20 uA supply current
• Rail-to-rail input capability for wide signal range
• Open-drain output configuration

Applications

• Battery-powered monitoring systems
• Threshold detection circuits
• General-purpose signal comparison tasks

Procurement Notes

Verify the specific suffix 'BIMX' against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Ensure the component meets RoHS compliance requirements for your region. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when dual comparators are required with minimal power draw. The open-drain output necessitates external pull-up resistors. Verify that the 18 mV input offset voltage meets system accuracy needs. Confirm that the 4 us response time is sufficient for the target application speed.

Part Context

This part belongs to the LMC6772 series of low-power CMOS comparators from Texas Instruments. It shares the SOIC-8 package form factor with other devices in the family but differs in channel count and output type compared to single-channel or push-pull variants.
