The PCM1737 is a CMOS, monolithic, integrated circuit which includes stereo digital-to-analog converters and support circuitry in a small SSOP-28 package. The data converters utilize Burr-Brown's enhanced multi-level delta-sigma architecture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1737 accepts industry standard audio data formats with 16- to 24-bit data, providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 192kHz are supported. A full set of user-programmable functions are accessible through a 4-wire serial control port which supports register write and read back functions.
