NIPPON PRECISION CIRCUITS INC.
3rd-order
Σ
, 2-channel D/A Converter
OVERVIEW
The SM5877AM is a 3rd-order
converter LSI for digital audio reproduction equip-
ment. It also incorporates an 8-times oversampling
digital filter and analog, post-converter lowpass fil-
ters.
Σ
, 2-channel D/A
The SM5877AM has digital deemphasis filter, atten-
uator, and soft mute circuits built-in. Double-speed
operation and low-voltage operation are also sup-
ported.
The SM5877AM operates from a 2.7 to 5.5 V supply,
and is available in 24-pin SSOPs.
