LM2903PT

Overview

The LM2903PT is a dual independent precision voltage comparator designed to operate from a single power supply over a wide range of voltages. It features a low supply current drain that is independent of the magnitude of the supply voltage, making it suitable for battery-operated systems and logic interface applications.

Why Choose This Part

The open-collector output allows for easy wired-OR configurations and level shifting to various logic voltages. It offers a wide common-mode input voltage range that includes ground, even when operated from a single power supply.

Applications

Getting Started

When designing with the LM2903PT, ensure an external pull-up resistor is connected to the output pin to establish the logic high level. Minimize parasitic capacitance on the output node to maintain fast switching speeds, and place a 0.1uF bypass capacitor close to the Vcc pin for stability.
