LMC7211BIM/NOPB

Overview

The LMC7211BIM/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SOIC-8 surface-mount package. It operates on a supply voltage range of 2.7 V to 15 V with a typical quiescent current of 14 µA. The device features rail-to-rail input capability extending down to -200 mV below the negative rail and provides a push-pull output 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. Common-mode rejection ratio is specified at 75 dB, while power supply rejection ratio reaches 80 dB. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Features rail-to-rail input capability allowing signal detection near the negative supply rail.
• Provides high-drive push-pull output stage suitable for direct interfacing with digital logic.
• Designed for low-power applications 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 official Texas Instruments documentation to confirm pinout compatibility and electrical tolerances. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs and a robust push-pull output is required. It is suitable for designs needing moderate drive strength without the complexity of open-drain configurations. Consider thermal performance and supply voltage constraints relative to the 2.7 V to 15 V operating range during circuit design.

Part Context

This part belongs to the LMC7211 series of tiny CMOS comparators manufactured by Texas Instruments. It serves as a general-purpose solution for analog signal comparison tasks. The device integrates high-impedance CMOS input stages with a complementary output structure, distinguishing it from open-drain variants like the LMC7221 within the same family.

Replacement Considerations

LMC7211BIMX/NOPB offers identical electrical characteristics but differs in packaging format (reel/cut tape versus tube). Verify that any alternative components maintain compatible input offset voltages and output drive capabilities to ensure circuit functionality remains unchanged.
