DESCRIPTION
The PCM1717 is a complete low cost stereo, audio digital-to-analog converter, including digital interpolation 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 I 2S data format. The digital filter performs an 8X interpolation function, as well as special functions such as soft mute, digital attenuation, and digital de-emphasis. The digital 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 required. Its low cost, small size, and single +5V power supply make it ideal for automotive CD players, bookshelf CD players, BS tuners, keyboards, MPEG audio, MIDI applications, set-top boxes, CD-ROM drives, CD-Interactive, and CD-Karaoke systems.
