TILM2901D
Overview
The LM2901D is a versatile quad differential comparator designed to operate from a single power supply over a wide range of voltages from 5V to 36V. It features four independent voltage comparators with open-collector outputs, allowing for easy integration into wired-AND logic circuits and level shifting applications. This device is specifically rated for an extended temperature range of -40C to 125C, making it suitable for demanding industrial environments.
Why Choose This Part
The quad-channel configuration in a single SOIC-14 package provides high functional density and saves PCB real estate. Its low quiescent current of 0.8mA at 5V and low input bias current of 0.25uA make it efficient for battery-powered or high-impedance sensing applications. The device's ability to handle input common-mode voltages down to ground simplifies circuit design in single-supply systems.
Applications
Key Specifications
Getting Started
To use the LM2901D, connect a pull-up resistor from the open-collector output to the desired logic level voltage. Ensure the input signals remain within the 0V to 36V range and do not exceed the supply rail by more than the specified limits. Decouple the VCC pin with a 0.1uF ceramic capacitor placed close to the device to minimize switching noise.
