LMC7211BIM

Overview

The LMC7211BIM is a single-channel analog comparator from the Texas Instruments LMC7211 series, housed in an SOIC-8 surface-mount package. It operates on a supply voltage ranging from 2.7 V to 15 V with a typical quiescent current of 14 µA. The device features rail-to-rail input capability and a push-pull output stage capable of sourcing or sinking 45 mA. Key electrical specifications include a maximum response time of 4 µs, an input offset voltage of 5 mV, and an input bias current of 0.4 pA. It provides a common-mode rejection ratio of 75 dB and a power supply rejection ratio of 80 dB, functioning within a temperature range of -40°C to +85°C.

Feature Summary

• Features rail-to-rail input capability for extended signal range utilization.
• Includes a push-pull output stage providing robust drive capability.
• Designed for low-power operation with minimal quiescent current consumption.

Applications

• General-purpose voltage threshold detection circuits
• Battery-powered monitoring systems requiring low standby current
• Signal conditioning interfaces for microcontrollers

Procurement Notes

Verify the specific suffix against the ordered part number, as packaging variations exist between tube and reel formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical operating conditions for the target application environment.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs and a push-pull output is required. Consider the 4 µs response time and 5 mV offset voltage limits for precision requirements. Evaluate the 14 µA supply current against system power budgets. Verify that the SOIC-8 package fits the available PCB footprint constraints.
