The STMicroelectronics TDA7803A-ZST is a four-channel Class-AB audio power amplifier for driving speakers, supplied in a 36-pin PowerSO package on tape and reel. Its listed output power rating is 47 W, and the device is in production status and RoHS compliant. Class-AB output stages are used in audio amplification where linearity and low distortion take priority over the higher efficiency of a Class-D design.
Four-channel audio power amplifiers are the standard head-unit and infotainment output stage, driving front-left, front-right, rear-left, and rear-right speakers from one device instead of four discrete amplifiers. Class-AB is chosen where audio quality and EMI behavior matter and the thermal budget allows it, since a Class-AB stage produces less switching noise than Class-D in an environment shared with radio tuners and sensitive receivers. The PowerSO package exists to move heat into the board or a heatsink, which is what makes the power rating usable in a sealed enclosure. Typical buyers are automotive audio and infotainment suppliers and vehicle OEMs, plus aftermarket head-unit and amplifier manufacturers and the contract manufacturers building those boards.
