The PCM1600(1) and PCM1601(1) are CMOS monolithic integrated circuits which feature six 24-bit audio digital-to-analog converters and support circuitry in either a LQFP-48 or MQFP-48 package. The digitalto-analog converters utilize Burr-Brown's enhanced multi-level, delta-sigma architecture, which employ 4th-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-noise performance and a high tolerance to clock jitter. The PCM1600 and PCM1601 accept industry-standard audio data formats with 16- to 24-bit audio data. Sampling rates up to 100kHz are supported. A full set of user-programmable functions are accessible through a 4-wire serial control port which supports register write and readback functions.
