Description

The PCM1792 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 PCM1792 provides balanced current outputs, allowing the user to optimize analog performance externally. The PCM1792 accepts PCM and DSD audio data formats, providing easy interfacing to audio DSP and decoder chips. The PCM1792 also accepts to interface 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 an SPI or I2C serial control port, which supports register write and readback functions. The PCM1792 also supports the time division multiplexed command and audio (TDMCA) data format.
