LP211DRE4

Overview

The LP211DRE4 is a single-channel low-power differential comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 5V to 30V or dual supplies of ±2.5V to ±15V. The device features an open-collector/open-emitter output configuration and delivers a typical response time of 1.2µs with a voltage gain of 100dB. It is housed in an 8-pin SOIC package, measuring 4.9mm x 3.91mm x 1.58mm, and supports an operating temperature range from -25°C to +85°C.

Feature Summary

• Low power consumption design suitable for battery-operated applications
• Open-collector and open-emitter outputs provide flexible interfacing options
• Single-supply operation capability simplifies circuit design

Applications

• Battery-powered monitoring systems
• Threshold detection circuits
• Logic interface adapters

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code against official datasheets. Ensure the ordering suffix matches the required RoHS compliance and lead-free specifications. Confirm the package type corresponds to the standard SOIC-8 footprint before integration into the production line.

Selection Notes

Select this component when low quiescent current is critical compared to standard comparators. Consider the 1.2µs propagation delay for timing-sensitive designs. Verify that the open-collector output requirements align with the system pull-up resistor constraints and logic level compatibility.

Part Context

This part belongs to the LMx11 family of differential comparators, offering enhanced performance over legacy counterparts. It serves as a direct replacement for the LP211D variant while adhering to modern environmental standards. The device maintains pin compatibility within the series for easy upgrades.

Replacement Considerations

LP211D is a confirmed substitute within the same product family.
