Overview
The TDA7563BPD, produced by STMicroelectronics, is a multifunction quad power amplifier designed specifically for car radio applications. This device utilizes BCD (Bipolar-CMOS-DMOS) technology and is available in the PowerSO36 package. It features a DMOS output stage, which ensures very low distortion and a clear, powerful sound. The TDA7563BPD is known for its high efficiency, reducing dissipated output power by up to 50% compared to conventional class AB solutions. It also includes a comprehensive diagnostics array that communicates the status of each speaker via the I2C bus.
