STMicroelectronics STA309B
The STA309B is a single-chip solution for digital audio processing and control in multichannel applications and provides output capabilities for FFX (full flexible 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 speaker mode, with 8 channel outputs in parallel, the STA309B can deliver 1 W (maximum).| Part No. | STA309B |
