SM5879AV

SM5879AV NIPPON PRECISION CIRCUITS INC. 3rd-order Σ∆, 2-channel D/A Converter OVERVIEW The SM5879AV is a 3rd-order ∑∆, two-channel D/A convertor LSI for digital audio reproduction equipment. This device incorporate NPC's molybdenumgate CMOS technology and incorporates an 8-times oversampling digital filter and analog 3rd-order ∑∆ post-converter low-pass filters. The SM5879AV also incorporates built-in digital bass boost and deemphasis filters, an attenuator, and soft mute function. Low-voltage operation is also supported. This device features a compact 24-pin VSOP package and a D/A converter that provides both compact size and low power consumption.
