LMC7215IM5/NOPB

Overview

The LMC7215IM5/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 V to 8 V and draws a typical operating supply current of 1 µA. The device features rail-to-rail input capability with a maximum input offset voltage of 8 mV and an input bias current of 0.05 pA. It provides push-pull output configuration and maintains a common-mode rejection ratio of 80 dB alongside a power supply rejection ratio of 90 dB. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated applications
• Rail-to-rail input stage maximizes dynamic input voltage range
• Push-pull output structure eliminates need for external pull-up resistors

Applications

• Battery-powered sensing systems requiring minimal quiescent current
• Threshold detection circuits in portable electronic devices
• Low-voltage signal conditioning interfaces

Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and specific packaging configuration. Confirm the SOT-23-5 footprint matches the design layout. Ensure the 2 V to 8 V supply range aligns with the target system voltage constraints. Validate that the 1 µA current draw meets the overall power budget requirements for the intended application environment.

Selection Notes

Select this component when low static current is critical compared to standard comparators. The rail-to-rail input allows operation closer to supply rails than non-rail-to-rail alternatives. The push-pull output simplifies interface design by removing external components. Consider the 8 mV offset voltage limit for precision threshold applications. Verify thermal performance within the specified -40°C to +85°C operational range.

Part Context

This device belongs to the LMC7215 series of low-power CMOS comparators from Texas Instruments. It is designed for general-purpose comparison tasks where power efficiency is prioritized over high-speed switching. The SOT-23-5 package offers a compact solution for space-constrained printed circuit board layouts. It serves as a specialized alternative to higher-current comparator families in ultra-low-power designs.
