Overview

The LM2901VQPWR is a quad-channel general-purpose differential comparator designed for operation over a wide range of voltages from a single or dual power supply. It features an open-collector output stage that allows for level shifting and logical OR-ing of outputs, making it highly versatile for system monitoring and signal processing.

Why Choose This Part

This device offers a high degree of integration with four independent comparators in a compact 14-TSSOP package. Its wide supply range of 2V to 32V and low input bias current of 0.25uA provide flexibility for both battery-powered and high-voltage industrial designs.

Applications

Limit Comparators
Used in window comparator circuits to detect if a voltage level is within a specific predefined range.
Oscillators
Utilized as a building block for square wave or pulse generators in low-frequency timing applications.
Logic Level Translation
The open-collector output allows the device to interface between different logic families with varying supply voltages up to 36V.
Industrial Control Systems
Suited for monitoring sensor thresholds in environments requiring an extended operating temperature range of -40C to 125C.

Getting Started

To evaluate this part, prototype using a TSSOP-14 breakout board on a standard breadboard. Ensure a pull-up resistor is connected to the open-collector output to establish the desired high-level logic voltage. Connect a 0.1uF ceramic bypass capacitor close to the VCC pin to minimize power supply noise.
