产品概述

描述

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.
