STMicroelectronics STA333IS
The STA333IS is an integrated circuit comprising digital audio processing, digital amplifier control and an FFX™ power output stage to create a high-power, single-chip FFX solution for all-digital amplification with high quality and high efficiency. The STA333IS power section consists of four independent half-bridge stages. The serial audio data input interface accepts all possible formats, including the popular I2S format.| Part No. | STA333IS |
