DESCRIPTION
The PCM1718 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. PCM1718 is fabricated on a highly
advanced 0.6碌 CMOS process. PCM1718 accepts 18-
bit normal input data format, or 16- or 18-bit I
2
S data
format.
The digital filter performs an 8X interpolation func-
tion, as well as special functions such as soft mute and
digital de-emphasis.
PCM1718 is suitable for a wide variety of cost-sensitive
consumer applications where good performance is re-
quired. Its low cost, small size, and single power supply
make it ideal for BS tuners, keyboards, MPEG audio,
PCMCIA audio cards (ZV port), MIDI applications,
and set-top boxes.
