Overview
The TDA7575BPD, produced by STMicroelectronics, is a multifunction dual-bridge power amplifier designed specifically for car radio applications. This device features a DMOS output stage, which ensures very low distortion and a clear, powerful sound. The TDA7575BPD is known for its high efficiency, derived from its internal exclusive structure, making it ideal for simplifying thermal management in high-power audio systems. It reduces the dissipated output power by up to 50% compared to conventional class AB solutions under average listening conditions.
