Σ
, 2-channel D/A converter
OVERVIEW
The SM5878AM/AV is a 3rd-order
D/A converter LSI for digital audio reproduction
equipment. It also incorporates an 8-times
oversampling digital filter and analog, post-converter
lowpass filters.
Σ
, 2-channel
The SM5878AM/AV has digital deemphasis filter,
attenuator, and soft mute circuits built-in. Double-
speed operation and low-voltage operation are also
supported.
SM5878AM/AV D/A converter incorporates 3rd-
order
∑
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.
