DESCRIPTION
The PCM1717 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. PCM1717 is fabricated on a highly
advanced 0.6µ CMOS process. PCM1717 accepts
16- or 18-bit normal input data format, or 16- or
18-bit I2S data format.
The digital filter performs an 8X interpolation func-
tion, as well as special functions such as soft mute,
digital attenuation, and digital de-emphasis. The digi-
tal filter features –35dB stop band attenuation and
±0.17dB ripple in the pass band.
PCM1717 is suitable for a wide variety of cost-sensitive
consumer applications where good performance is re-
quired. 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.
