SM588x series
Audio 3rd-order ΣΔ D/A Converter
The ΣDECO SM588x
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, ΣΔ
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.
