Description
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). 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).
