TILM2901PWR

Overview

The LM2901PWR is a quadruple independent precision voltage comparator designed to operate from a single power supply over a wide range of voltages. This device features four open-collector outputs, allowing for easy level shifting and wired-OR logic configurations in complex timing or level-detection circuits. It is engineered for stable operation across a broad temperature range of -40C to 125C, making it suitable for both industrial and consumer environments.

Why Choose This Part

The LM2901PWR offers high versatility with a wide supply range of 5V to 36V and a low quiescent current of 0.8mA at 5V. Its 14-TSSOP package provides a compact footprint for high-density boards while maintaining four independent channels, and the open-collector outputs support sink currents up to 21mA for driving LEDs or relays directly.

Applications

Getting Started

To evaluate this component, integrate it into a breadboard using a TSSOP-to-DIP adapter or use a generic operational amplifier evaluation module that supports 14-pin TSSOP footprints. Ensure a pull-up resistor is connected to the output pin to observe logic transitions, as the open-collector architecture cannot drive a high signal on its own.
