LMC7221AIM5/NOPB

Overview

The LMC7221AIM5/NOPB is a single-channel, low-voltage CMOS analog comparator manufactured by Texas Instruments. It features rail-to-rail input and output capabilities, allowing operation with supply voltages ranging from 2.7V to 15V. The device offers a typical quiescent current of 14µA and a maximum propagation delay of 10µs. It utilizes a SOT-23-5 surface-mount package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail input and output functionality for extended dynamic range
• Low power consumption suitable for battery-operated applications
• Push-pull output stage providing strong drive capability

Applications

• Battery-powered sensing systems
• Threshold detection circuits
• General-purpose voltage monitoring

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 'M5' designation corresponds to the SOT-23-5 package variant. Ensure the component matches the exact part number for pinout and electrical specification compatibility in existing designs.

Selection Notes

Select this component when rail-to-rail input/output performance is required at low supply voltages. Compare propagation delay and quiescent current against other comparators if speed or power efficiency are critical constraints. Verify that the SOT-23-5 package fits the available PCB footprint.

Part Context

This part belongs to the LMC72xx series of low-voltage CMOS comparators from Texas Instruments. It shares functional similarities with the LMC7211 but may differ in specific electrical parameters or package options. The series is designed for applications requiring low power and wide common-mode input voltage ranges.

Replacement Considerations

LMC7211AIM5X/NOPB is listed as a substitute in distributor databases.
