The following is the circuit diagram of [20W audio power amplifier LM1875 pin circuit diagram] The LM1875 is a monolithic power amplifier that provides consumers with very low distortion and high quality performance in audio applications. When the LM1875 is powered by a ±25V supply, it can output 20W of power and drive a 4Ω or 8Ω load. When powered by a ±30V supply, it can output 30W and drive an 8Ω load. The amplifier has a minimum of peripheral components, and the protection circuit includes internal current limiting and thermal shutdown. The LM1875 uses advanced circuit design techniques to achieve minimal distortion, even at large output power levels. The LM1875 also features high gain, fast slew rate, wide power bandwidth, large output voltage swing, high current capability, and a very wide supply range. The amplifier is internally compensated to provide stability at gains of 10 or higher. The LM1875 can be used in high quality audio systems, bridge amplifiers, stereo players, servo system amplifiers, instrumentation amplifiers, etc. The pinout of the LM1875 is shown in the figure.
