SM5878AV

SM5878AM/AV NIPPON PRECISION CIRCUITS INC. 3rd-order Σ∆, 2-channel D/A converter OVERVIEW The SM5878AM/AV is a 3rd-order Σ∆, 2-channel D/A converter LSI for digital audio reproduction equipment. It also incorporates an 8-times oversampling digital filter and analog, post-converter lowpass filters. The SM5878AM/AV has digital deemphasis filter, attenuator, and soft mute circuits built-in. Doublespeed operation and low-voltage operation are also supported. SM5878AM/AV D/A converter incorporates 3rdorder ∑∆ modulator and DEM (Dynamic Element Mating) circuits for high performance, even in the presence of clock jitter. The SM5878AM/AV operates from a 4.5 to 5.5 V supply, and is available in 24-pin SSOP or VSOPs.
