Product Introduction

Overview

The TDA7561H, manufactured by STMicroelectronics, is a multifunction quad power amplifier designed specifically for car radio applications. This device utilizes BCD (Bipolar-CMOS-DMOS) technology and is packaged in a Flexiwatt25 format, available in both vertical and horizontal configurations. The TDA7561H features a DMOS output stage, which ensures very low distortion and a clear, powerful sound. It also includes a comprehensive diagnostics array that communicates the status of each speaker through an I2C bus, making it highly flexible and reliable for automotive audio systems.
