LMC7225IM5/NOPB

Overview

The LMC7225IM5/NOPB is a single-channel analog comparator from Texas Instruments, housed in a SOT-23 package. It operates on a supply voltage range of 2 V to 8 V with an operating supply current of 1 uA. Key electrical specifications include an input offset voltage (Vos) of 6 mV and an input bias current (Ib) of 50 fA. The device features an open-drain output type and has a response time of 24 us. It functions within a temperature range of -40 C to +85 C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Rail-to-rail input capability for maximum dynamic range
• Open-drain output configuration for flexible interfacing

Applications

• Battery-powered sensing systems
• Threshold detection circuits
• Low-voltage signal conditioning

Procurement Notes

Verify the specific suffix and manufacturer details against official datasheets to ensure compatibility. Confirm RoHS compliance status and packaging options such as cut tape or reel availability through authorized distributors. Check for any recent product lifecycle changes or obsolescence notices directly from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when low quiescent current is critical alongside rail-to-rail input requirements. The open-drain output necessitates an external pull-up resistor, which should be chosen based on the target logic level and switching speed requirements. Ensure the supply voltage remains within the 2 V to 8 V operational window for optimal performance.

Part Context

This part belongs to the LMC7225 series of tiny comparators designed for space-constrained and energy-efficient designs. It shares the SOT-23 footprint with other low-power devices in the family, facilitating compact PCB layouts. The series emphasizes minimal power usage while maintaining adequate speed for general-purpose comparison tasks.
