STMicroelectronics' new audio amplifier IC
STMicroelectronics announced the new FDA901 class-D audio amplifier IC with a semiconductor design that incorporates the audio design of Alps Alpine Co., Ltd. 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. It is equipped with a range of self-diagnostics and other advanced functions to measure real-time speaker current and impedance, factors that the company says is prized in the next-generation car audio market for diagnostics, and to compensate for loudspeaker imperfections.
"For many years, Alpine Electronics has collaborated closely with ST and shared a wealth of sound-related knowledge,” said Mr.Yukihiro Kobori, Sound Meister, Sound Design Division of Alps Alpine. “We are very pleased that ST's audio amplifier IC and our company's car audio technology and business have been able to grow together. We have worked with ST to design a class-D audio amplifier IC able to raise the level of audio quality across the entire car audio industry, while contributing to Alps Alpine's goal of developing the highest level of car audio."
Starting from the adoption in 39 models of Alpine’s “ALL New BigX series” aftermarket car-navigation system to be released in the first half of 2020, the FDA901 will expand its market to several major carmakers.
"In car audio, the amplifier IC is a key component that greatly affects sound quality,” said Luca Celant, General Manager, Automotive Infotainment Division, Automotive & Discrete Group, STMicroelectronics. “Drawing on the close cooperative relationship that we have built with Alps Alpine’s engineering team through class-AB audio amplifiers, this new class-D audio amplifier represents another milestone for our class-D audio amplifiers and sets a new bar for audio performance."
The FDA901 is in volume production. Budgetary pricing is $9.10 for orders of 1000 pieces and the product will be available through distributors by April 2020.
