DSD1791中文资料113dB SNR 立体声音频 DAC（硬件控制）数据手册TI规格书

描述 Description

The DSD1791 is a monolithic CMOS integrated circuit that includes stereo digital-to-analog converters and support circuitry in a small 28-lead SSOP package. The data converters use TI’s advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The DSD1791 provides balanced voltage outputs, allowing the user to optimize analog performance externally. The DSD1791 accepts PCM and DSD audio data formats, providing easy interfacing to audio DSP and decoder chips. The DSD1791 also accepts interface to external digital filter devices (DF1704, DF1706, PMD200). Sampling rates up to 200 kHz are supported. A full set of user-programmable functions is accessible through a three-wire serial control port. The DSD1791 also supports the time-division-multiplexed command and audio (TDMCA) data format.
