Overview

The LM2903DMR2G is a dual independent precision voltage comparator designed to operate over a wide range of voltages from a single power supply. This general-purpose component features an open-collector output, allowing it to interface easily with various logic families including TTL, CMOS, and MOS.

Why Choose This Part

It offers high-voltage flexibility with an operating range of 2V to 36V and can handle input voltages up to 36V regardless of the supply voltage. The 8-MSOP (Micro8) package provides a significant space-saving footprint for dense PCB designs while maintaining dual comparator functionality.

Applications

Limit Comparators
Monitoring voltage levels against a reference to trigger alarms or safety shutdowns.
Zero Crossing Detectors
Identifying the point where an AC signal crosses the ground reference for timing or phase control.
Clock Square Wave Generators
Converting sinusoidal or irregular waveforms into clean digital clock signals.
Voltage Level Translators
Interfacing between different logic voltage domains using its open-collector output structure.
