STA309B - Multichannel digital audio processor

General 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.

Key Features

  • 8 channels of 24-bit FFX® >100 dB SNR and dynamic range Selectable 32 kH-192 kHz input sampling rates 6 channels of DSD/SACD and PDM input Digital gain/attenuation +58 dB to -100 dB in 0.5 dB steps Advanced “pop-free” operation Digital “pop-free” operation for single-ended mode Soft volume update Individual channel and master gain/attenuation plus channel trim (-10 dB to +10 dB) Up to 10 independent 32-bit.
