LMC7225IMX

Overview

The LMC7225IMX is a single-channel analog comparator manufactured by Texas Instruments, designed for ultra-low power applications. It features an open-drain output and operates within a supply voltage range of 2 V to 8 V. Key electrical characteristics include a maximum input bias current of 50 fA, an input offset voltage of 6 mV, and an operating supply current of 1 uA. The device provides a response time of 24 us and functions reliably across a temperature range from -40°C to 85°C.

Feature Summary

• Ultra-low input bias current capability
• Open-drain output configuration
• Low power consumption design

Applications

• Battery-powered instrumentation
• Portable measurement devices
• High-impedance sensor interfaces

Procurement Notes

Verify the specific suffix 'IMX' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and supply voltage ranges before integration into final designs.

Selection Notes

Select this component when minimizing quiescent current is critical. The open-drain output requires appropriate pull-up components. Verify that the 24 us response time meets system timing requirements compared to faster comparator alternatives.

Part Context

This part belongs to the LMC7225 family of precision comparators. It shares core specifications with variants like the LMC7225IM5-NOPB but differs in packaging and reel configuration. The series is characterized by FET-input stages enabling extremely low bias currents suitable for sensitive signal detection.

Replacement Considerations

Check for direct pin-compatible equivalents such as the LMC7225IM5-NOPB. Confirm that any substitute maintains the same open-drain output structure and low bias current performance levels.
