LMC7215QIM5/NOPB

Overview

The LMC7215QIM5/NOPB is a single-channel analog comparator manufactured by Texas Instruments, designed for low-power applications. It operates within a supply voltage range of 2 V to 8 V and consumes only 1 uA of operating current. The device features rail-to-rail input capability, ensuring compatibility with various signal levels. Key electrical specifications include an input offset voltage of 8 mV and an input bias current of 0.05 pA. It provides push-pull output configuration and offers high common-mode rejection ratio (CMRR) of 80 dB and power supply rejection ratio (PSRR) of 90 dB. The component functions reliably across a temperature range from -40 C to +85 C.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Rail-to-rail input stage for maximum dynamic range
• Push-pull output driver for direct logic interface

Applications

• Battery-powered monitoring circuits
• Low-voltage threshold detection systems
• Portable electronic devices requiring minimal quiescent current

Procurement Notes

Verify the 'Q' suffix indicates automotive qualification requirements specific to this part number. Confirm the SOT-23-5 package orientation and pinout match your PCB footprint design. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance documentation as indicated in manufacturer records. Validate that the push-pull output type aligns with your downstream circuitry needs.

Selection Notes

Select this component when ultra-low static current is critical compared to standard comparators. Consider the 8 mV offset voltage for precision requirements. The rail-to-rail input allows use with signals swinging close to supply rails. Compare against LMC7215 variants if different packaging or non-automotive grades are acceptable. Evaluate the push-pull output against open-drain alternatives for drive strength needs.

Part Context

This part belongs to the LMC7215 family of tiny CMOS comparators from Texas Instruments. It shares core specifications with the standard LMC7215IM5/NOPB but includes the 'Q' designation for qualified automotive grade performance. The family is characterized by low voltage operation and minimal power usage. It serves as a compact solution for space-constrained designs requiring reliable comparison functions.

Replacement Considerations

LMC7215IM5/NOPB is the standard commercial grade equivalent with identical electrical characteristics.
