OVERVIEW

The ΣDECO SM588× series, fabricated using NPC’s Molybdenum-gate CMOS process, are D/A converter ICs for digital audio, that provide all the basic converter functions in miniature 8-pin packages. They each feature built-in 8-times oversampling digital filter, Σ? jitter-compensated D/A converter, and post-analog lowpass filter converter stages required for digital audio. They can sample at up to 96kHz for 16 or 24-bit input word length. A type with built-in deemphasis filter is also available for applications requiring deemphasis.
