TILM2901N
Overview
The LM2901N is a quad independent precision voltage comparator designed to operate from a single power supply over a wide range of voltages from 2V to 36V. This version comes in a 14-pin PDIP through-hole package, making it ideal for prototyping, educational projects, and legacy system maintenance. It features open-collector outputs, allowing for easy integration into various logic levels through the use of external pull-up resistors.
Why Choose This Part
The through-hole PDIP package allows for easy use with standard breadboards and sockets without needing surface-mount adapters. Its wide operating temperature range of -40C to 125C and 36V maximum supply voltage ensure reliability in harsh industrial and automotive environments.
Applications
Key Specifications
Getting Started
To use the LM2901N, connect a pull-up resistor from the output pin to your desired logic voltage level, as the open-collector architecture cannot drive high signals on its own. Ensure the common-mode input voltage remains within the specified 0V to VCC-1.5V range for accurate switching. For prototyping, it can be plugged directly into a standard breadboard or a 14-pin DIP socket.
