OVERVIEW

The

Σ

DECO 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 fil-

ter 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.
