STMicroelectronics’ Integrated Automotive Audio Amplifier Combines High-Resolution Sound with Class-G Efficiency

STMicroelectronics announced its latest TDA7901 single-chip quad-bridge automotive amplifier using the company's advanced BCD (Bipolar-CMOS-DMOS) technology, integrates a buck controller for class-G power switching, and supports high-resolution audio. The TDA7901 features a full D/A converter, digital input for direct connection to I2S (or TDM) and powerful MOSFET output stages. A market-unique combination that STMicro says will be ideal for listening and high efficiency.

THX, renowned for the certification of world-class cinemas and electronic devices, has partnered with Triad Semiconductor to manufacture its revolutionary TSTHX-88 headphone amplifier ASIC. According to THX, the THX AAA Headphone Amplifier technology offers the world’s lowest levels of distortion and noise alongside incredibly low power consumption and it outperforms every other amplifier technology in the marketplace.
