DESCRIPTION

The PCM1718 is a complete low cost stereo, audio

digital-to-analog converter, including digital interpolation

filter, 3rd-order delta-sigma DAC, and analog

output amplifiers. PCM1718 is fabricated on a highly

advanced 0.6m CMOS process. PCM1718 accepts 18-

bit normal input data format, or 16- or 18-bit I2S data

format.

The digital filter performs an 8X interpolation function,

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 required.

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.
