The PCM1717 is a complete low cost stereo, audiodigital-to-analog converter, including digital interpo-lation filter, 3rd-order delta-sigma DAC, and analogoutput amplifiers. PCM1717 is fabricated on a highlyadvanced 0.6µ CMOS process. PCM1717 accepts16- or 18-bit normal input data format, or 16- or18-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-sensitiveconsumer applications where good performance is re-quired. Its low cost, small size, and single +5V powersupply 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.
