LP2901N TI Comparator | 14-PDIP | Quad, Low Power, Open Collector

Product Overview

The LP2901N from Texas Instruments is a quad low-power voltage comparator designed for applications requiring low power consumption and high accuracy. It features an open-collector output stage, making it suitable for driving loads such as relays, LEDs, and logic circuits. The device operates from a single power supply of 2V to 30V or dual supplies of ±1V to ±15V, offering flexibility in various system designs. With a typical supply current of only 0.4mA per comparator, the LP2901N is ideal for battery-powered and portable equipment.
