Overview
The LM2902PWR is a quad operational amplifier produced by Texas Instruments. It is part of the next-generation LM324B and LM2902B series, which are designed to be drop-in replacements for all versions of the LM224, LM324, and LM2902 devices. These amplifiers are known for their high voltage capability, low offset voltage, and robust environmental tolerance, making them suitable for a wide range of cost-sensitive applications.
