STMicroelectronics Announces New-Generation Class-D Audio Amplifier IC Developed in Cooperation with Alps Alpine

STMicroelectronics announced the new FDA901 class-D audio amplifier IC, a new design that incorporates the world-class audio expertise of Japanese manufacturer of car audio equipment, Alps Alpine. The new ST chip aims to contribute to the creation of multi-function, high-fidelity car audio systems that fuse the high efficiency of class-D amplifiers with the high-quality sound of ST’s class-AB amplifiers.

STMicroelectronics announced its second-generation digital audio amplifiers with internal 24-bit DAC conversion, bringing increased performance in comparison to its original products introduced in 2012. The new FDA801 and FDA801B 4-channel class-D components simplify system design and lower cost for car-radio suppliers, allowing for more than 40% power savings compared to standard class-D amplifiers.
