Description

The STA309A is a single chip solution for digital

audio processing and control in multi-channel

applications. It provides output capabilities for

DDX?. In conjunction with a DDX? power device,

the STA309A provides high-quality,

high-efficiency, all digital amplification. The device

is extremely versatile, allowing inputs of most

digital formats including 6.1/7.1-channel and

192 kHz, 24-bit DVD-audio, DSD/SACD. In 5.1

applications the additional 2 channels can be

used for audio line-out or headphone drive. In

speaker mode, with 8 channel outputs in parallel,

the STA309A can deliver more than 1 W.
