Overview
The LM324PWRE4 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. These devices are unity-gain stable and provide four high-voltage (up to 36V) op amps, making them suitable for a wide range of cost-sensitive applications. The LM324PWRE4 is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) and operates over a temperature range of 0°C to 70°C.
