Product Introduction

Overview

The TDA7563B, produced by STMicroelectronics, is a multifunction quad power amplifier designed specifically for car radio applications. It utilizes BCD (Bipolar, CMOS, DMOS) technology and features a DMOS output stage, which ensures very low distortion and a clear, powerful sound. This amplifier is available in Flexiwatt27 and PowerSO36 packages, making it versatile for various automotive audio systems. The TDA7563B is known for its high efficiency, particularly in the class SB mode, which reduces the dissipated output power by up to 50% compared to conventional class AB solutions. This makes it an ideal choice for high-power audio systems in vehicles, simplifying thermal management and enhancing overall performance.
