3rd-order

危鈭?/div>

, 2-channel D/A Converter

OVERVIEW

The SM5879AV is a 3rd-order

鈭戔垎

, two-channel D/A

convertor LSI for digital audio reproduction equip-

ment. This device incorporate NPC's molybdenum-

gate CMOS technology and incorporates an 8-times

oversampling digital 铿乴ter and analog 3rd-order

鈭戔垎

post-converter low-pass 铿乴ters.

The SM5879AV also incorporates built-in digital

bass boost and deemphasis 铿乴ters, an attenuator, and

soft mute function. Low-voltage operation is also

supported.

This device features a compact 24-pin VSOP pack-

age and a D/A converter that provides both compact

size and low power consumption.
