Overview
The LM2902DR is a quad operational amplifier (op-amp) produced by Texas Instruments. It is part of the next-generation LM324B and LM2902B series, which are designed to offer improved specifications and enhanced performance compared to their predecessors. These devices are unity-gain stable and feature four high-voltage (36V) op-amps, making them suitable for a wide range of cost-sensitive applications. The LM2902DR is packaged in a 14-pin SOIC (D) package and operates over a temperature range of -40°C to 125°C.
