LM324 Quadruple Operational Amplifier DIP-14

LM324 is a low-power, quadruple operational amplifier IC that consists of four independent high-gain op-amps in a single DIP-14 package. It is commonly used in signal conditioning, sensor interfacing, voltage follower circuits, and audio amplification due to its wide power supply range and low offset voltage. The LM324 is ideal for general-purpose applications in industrial, automotive, and consumer electronics.
