LMC7215IMX/NOPB

Overview

The LMC7215IMX/NOPB is a single-channel analog comparator from Texas Instruments, housed in an SOT-23-5 surface-mount package. It operates on a supply voltage range of 2 V to 8 V with a typical operating supply current of 1 µA. Key electrical specifications include a maximum input offset voltage (Vos) of 8 mV and an input bias current (Ib) of 0.05 pA. The device features rail-to-rail inputs and a push-pull output. It provides a common-mode rejection ratio (CMRR) of 80 dB and a power-supply rejection ratio (PSRR) of 90 dB. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low quiescent current consumption suitable for battery-powered applications
• Rail-to-rail input capability allows operation near supply rails
• Push-pull output stage provides defined logic levels without external pull-ups
• High input impedance minimizes loading effects on signal sources

Applications

• Battery-operated portable devices requiring low power monitoring
• Threshold detection circuits in consumer electronics
• Temperature sensing interfaces using thermistors or RTDs
• Voltage level shifting between different logic domains

Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific tape-and-reel packaging configuration. Confirm the SOT-23-5 footprint matches the design layout. Check for RoHS directive adherence if required by regional regulations. Ensure the operating voltage range aligns with the system's power supply constraints.

Selection Notes

Select this component when ultra-low static current is critical compared to standard comparators. The rail-to-rail input feature is essential for single-supply systems where signals swing close to ground or Vcc. The push-pull output simplifies interface design by eliminating the need for external pull-up resistors. Consider the 8 mV offset voltage limit for precision threshold applications.

Part Context

This device belongs to the LMC7215 series of low-power CMOS comparators manufactured by Texas Instruments. It is designed as a general-purpose solution for applications demanding minimal power consumption while maintaining adequate speed and accuracy. The SOT-23-5 package offers a compact form factor suitable for space-constrained printed circuit board designs.

Replacement Considerations

Consult official substitution guides for equivalent single-channel comparators with similar low-current specifications. Verify pin compatibility and electrical parameter alignment before replacing existing components in production designs.
