DESCRIPTION
The PCM1712 is a complete low cost stereo, audio
digital-to-analog converter, including digital interpo-
lation filter, 3rd-order delta-sigma DAC, and analog
output amplifiers. PCM1712 accepts 16-bit normal
input data (MSB first, right justified), or 16-bit IIS
data (32-bits per word, continuous clock).
The digital filter performs an 8X interpolation func-
tion, as well as special functions such as soft mute,
digital attenuation, de-emphasis and double-speed
dubbing.
PCM1712 is suitable for a wide variety of cost-sensi-
tive consumer applications where good performance is
required. Its low cost, small size and single +5V power
supply make it ideal for automotive CD players, book-
shelf CD players, BS tuners, keyboards, MPEG audio,
MIDI applications, set-top boxes, CD-ROM drives,
CD-Interactive and CD-Karaoke systems. PCM1712
has the same pinout functions as PCM1710.
