LMC7211AIM5/NOPB

Overview

The LMC7211AIM5/NOPB is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates within a supply voltage range of 2.7 V to 15 V and draws a typical quiescent current of 14 µA. 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. The device features a push-pull output stage capable of sourcing or sinking up to 45 mA per channel. It provides a common-mode rejection ratio of 75 dB and a power supply rejection ratio of 80 dB, with rail-to-rail input capability.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Rail-to-rail input capability for extended signal range utilization
• High output drive strength for direct interfacing with digital logic

Applications

• Battery-powered sensing systems requiring minimal standby current
• Threshold detection circuits in portable instrumentation
• General-purpose voltage monitoring in low-power embedded designs

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required operating conditions. Confirm that the SOT-23-5 package dimensions align with PCB footprint constraints. Check for any recent product change notices regarding manufacturing site transitions or material updates. Ensure compliance with RoHS directives if applicable to the target market regulations.

Selection Notes

Select this component when low static current and high input impedance are critical design parameters. The rail-to-rail input feature allows for full-scale signal processing without headroom loss. Consider the 45 mA output drive capability for direct load driving without additional buffering stages. Evaluate the 5 mV offset voltage tolerance against required accuracy thresholds in precision comparison tasks.

Part Context

This part belongs to the LMC7211 series of CMOS comparators designed for low-voltage, low-power applications. It shares functional similarities with other members of the family but differs in packaging and specific ordering suffixes. The device integrates standard comparator functionality with enhanced input characteristics suitable for modern low-energy electronic systems.

Replacement Considerations
