Part Overview
Description
The PCM1738 is a CMOS integrated circuit (IC) that includes stereo digital-to-analog converters (DACs) and support circuitry in a small SSOP-28 package. The data converters use an advanced segment DAC architecture for excellent dynamic performance and improved tolerance to clock jitter. The PCM1738 provides balanced current outputs, allowing for external optimization of analog performance. It accepts industry-standard audio data formats with 16- to 24-bit data, enabling easy interfacing with audio DSP and decoder chips. Sampling rates up to 200 kHz are supported. The PCM1738 also has two optional modes of operation: an external digital filter mode (for use with the DF1704, DF1706, and PMD200) and a DSD decoder interface for SACD playback applications. A full set of user-programmable functions is accessible through a 4-wire serial control port that supports register write and read functions.
