DESCRIPTION

The STA306 is a single chip solution for digital audio processing and control in multi-channel applications. It provides output capabilities for DDXTM (Direct Digital Amplification). In conjunction with a DDXTM power device, it provides high-quality, high-efficiency, all digital amplification. The device is extremely versatile allowing for input of most digital formats including 192kHz, 24-bit DVD-Audio.
