LMC7211AIM5X

Overview

The LMC7211AIM5X is a single-channel CMOS analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 15V (single) or ±1.35V to ±7.5V (dual). Key electrical specifications include a maximum input offset voltage of 5mV at 5V, a maximum input bias current of 0.04pA at 5V, and a typical quiescent current of 14µA. The device features a push-pull output capable of sourcing 30mA, with a maximum propagation delay of 10µs. Common-mode rejection ratio (CMRR) is typically 75dB, and power supply rejection ratio (PSRR) is typically 80dB. It is housed in an SOT-23-5 package and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Rail-to-rail input capability allows operation with common-mode voltages extending below the negative rail.
• Ultra-low input bias current ensures minimal loading on high-impedance signal sources.
• Push-pull output stage provides direct interfacing with digital logic circuits without external pull-up resistors.

Applications

• Battery-powered monitoring systems requiring low quiescent current
• Threshold detection in precision measurement instrumentation
• Signal conditioning for high-impedance sensor interfaces

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance and lead-free soldering requirements against specific project standards. Validate that the SOT-23-5 footprint matches the design layout. Ensure thermal management considerations align with the specified operating temperature range during integration.

Selection Notes

Select this component when rail-to-rail input compatibility and ultra-low bias current are critical. Compare performance against the LMC7211AIMX/NOPB if an SOIC-8 package is preferred for higher channel density or different mounting constraints. Evaluate the LMV721IDCKR only if operational amplifier functionality with higher bandwidth is required instead of pure comparison.

Part Context

This part belongs to the LMC7211 series of low-power, high-voltage comparators from Texas Instruments. It is designed for applications demanding high input impedance and wide supply voltage ranges. The AIM5X suffix denotes the industrial temperature grade and specific SOT-23-5 packaging configuration.

Replacement Considerations

LMC7211AIM5X/NOPB is a confirmed equivalent substitute offering identical electrical characteristics and pinout compatibility within the same SOT-23-5 package format.
