STMicroelectronics introduces new Class D audio amplifier IC

     STMicroelectronics, a leading global semiconductor company, announced the introduction of the new FDA901 Class D audio amplifier integrated circuit, whose semiconductor design incorporates Alps Alpine Co., a major Japanese manufacturer of automotive audio equipment. Ltd.) world-class audio design expertise, and infocomm equipment. The goal of the new chip is to create a versatile, high-fidelity car audio system that combines the high efficiency of a Class D amplifier with the high-quality sound of a Class ST AB amplifier.

     The FDA901 features low residual noise, low distortion rate, flat frequency response through feedback technology, and low EMI levels. It provides high purity audio performance by minimizing the loss of audio signals. Equipped with a range of self-diagnostic and other advanced features that measure speaker current and impedance in real time, diagnose and compensate speaker defects as important factors in the next generation automotive audio market, the FDA901 is a Class D audio amplifier integrated circuit that simultaneously displays extremely high quality sound and innovative features that increase sound fidelity.

     "Alps Electronics has worked closely with ST over the years to share a wealth of sound-related knowledge," said Yukihiro Kobori of sound Meister, Alps' sound design department. . "We are very pleased that ST's audio amplifier IC and our company's automotive audio technology and business will grow together. "In collaboration with ST, we have designed a Class D audio amplifier IC that will raise the level of audio quality across the automotive audio industry, while contributing to Alpine's goal of developing the highest level of automotive audio."

     Starting with Alpine's 39 "All-new BigX Series" aftermarket automotive navigation systems, which will be released in the first half of 2020, the FDA901 will extend the market to several major automakers."In in-car audio, the amplifier IC is a key component that greatly influences sound quality," says Luca Celant, General Manager, Automotive Infotainment Division, Automotive and Discrete Group, STMicroelectronics. "Leveraging the close working relationship we have established with the Alpine Engineering team through our AB Class audio amplifiers, this new Class D audio amplifier represents another milestone in our Class D audio amplifiers and sets a new standard for audio performance."
