Multichannel digital audio processor with FFX?

Description

The STA309B is a single-chip solution for digital audio processing and control in multichannel

applications and providesoutput capabilities for FFX (full flexible amplification). In conjunction with

an FFX power device, it provides high-quality, high-efficiency, all-digital amplification. The device

is extremely versatile, allowing for input of most digital formats including 6.1/7.1-channel and

192 kHz, 24-bit DVD-audio, DSD/SACD and PDM for MEMS microphone inputs. In the 5.1

application, the additional 2 channels can be used for audio line-out or headphone drive. In speaker mode, with 8 channel outputs in parallel, the STA309B can deliver 1 W (maximum).
