Texas Instruments PCM1795DB

Description
The PCM1795 is a monolithic CMOS integrated circuit that includes stereo digital-to-analog converters (DACs) and support circuitry in a small SSOP-28 package. The data converters use TI's advanced segment DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1795 provides balanced current outputs, allowing the user to optimize analog performance externally.
PCM1795 accepts pulse code modulation (PCM) and direct stream digital (DSD) audio data formats, providing an easy interface to audio digital signal processors (DSPs) and decoder chips. The PCM1795 also interfaces with external digital filter devices such as the DF1704, DF1706, and the PMD200 from Pacific Microsonics. Sampling rates up to 200 kHz are supported. A full set of user-programmable functions is accessible through an SPI or PC serial control port that supports register write and readback functions. The PCM1795 also supports the time-division-multiplexed (TDM) command and audio (TDMCA) data format.
