LMC7211BIM5X/NOPB

Overview

The LMC7211BIM5X/NOPB is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOT-23-5 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 and a push-pull output stage capable of sourcing or sinking 45 mA. Key electrical specifications include a maximum input offset voltage of 5 mV, an input bias current of 0.4 pA, and a propagation delay of 4 µs. Common-mode rejection ratio (CMRR) is specified at 75 dB, while power supply rejection ratio (PSRR) reaches 80 dB. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input capability for full common-mode voltage range utilization
• Push-pull output stage providing robust drive capability without external pull-up resistors
• Ultra-low power consumption suitable for battery-operated applications
• High input impedance CMOS architecture minimizing loading effects

Applications

• Battery-powered sensing systems requiring low standby current
• Threshold detection circuits in portable electronic devices
• Over-voltage and under-voltage protection loops
• Window comparator configurations for signal monitoring

Procurement Notes

Verify the specific suffix 'M5' against official Texas Instruments documentation to confirm the SOT-23-5 package designation, as standard listings often reference the SOIC-8 variant. Ensure the 'NOPB' indicator confirms lead-free and RoHS compliance status per current environmental regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate availability and authenticity before procurement.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs and a compact SOT-23-5 footprint is required. The push-pull output eliminates the need for external pull-up components, simplifying board layout. Consider the 4 µs response time for applications where moderate speed is acceptable alongside ultra-low power constraints. Verify that the 15 V maximum supply voltage aligns with the system's power rails.

Part Context

This device belongs to the LMC7211 series of tiny CMOS comparators from Texas Instruments. It shares functional similarities with the LMC7221 but differs in output topology, offering a push-pull structure instead of open-drain. The family is designed for general-purpose comparison tasks where low power and wide supply voltage operation are critical design parameters.
