STA308A Multi-channel digital audio processor with DDX(TM)

The STA308A is a single chip solution for digital audio processing and control in multi-channel applications. It provides output capabilities for DDX® (Direct Digital Amplification). In conjunction with a DDX®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 192kHz, 24-bit DVD-Audio, DSD/SACD. In 5.1 application the additional 2 channels can be used for line-out or loadphone drive. In speaker mode, with 8 channel outputs in parallel, the STA308A can deliver 1W (maximum).
