New-generation class-D amplifier boosts car-audio sound quality
STMicroelectronics announced the new FDA901 class-D audio amplifier IC, with a semiconductor design that incorporates the world-class audio design expertise of Alps Alpine, a major Japanese manufacturer of car audio equipment and information communication equipment. The new 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.
The FDA901 features low residual noise, a low distortion ratio, a flat frequency response achieved through feedback technology, and low EMI levels. It delivers high-purity audio performance by minimizing dropout of audio signals. Equipped with a range of self-diagnostics and other advanced functions to measure real-time speaker current and impedance, factors prized in the next-generation car audio market for diagnostics and to compensate for loudspeaker imperfections, FDA901 is a class-D audio amplifier IC that simultaneously shows both extremely high-quality sound and very innovative features that improve sound fidelity.
The FDA901 is in volume production. Budgetary pricing is $9.10 for orders of 1,000 pieces and the product will be available through distributors by April 2020.
