Overview
The STA309A13TR, produced by STMicroelectronics, is a multi-channel digital audio processor that integrates advanced DDX® (direct digital amplification) technology. This single-chip solution is designed for digital audio processing and control in various multi-channel applications. It supports a wide range of digital formats, including 6.1/7.1-channel and 192 kHz, 24-bit DVD-audio, as well as DSD/SACD inputs. The device is highly versatile, allowing for high-quality, high-efficiency all-digital amplification when used with a DDX® power device. In 5.1 applications, the additional two channels can be utilized for audio line-out or headphone drive, and in speaker mode, it can deliver more than 1 W with 8 channel outputs in parallel.
