DESCRIPTION

The PCM1725 is a complete low cost stereo audio

digital-to-analog converter (DAC), operating off of a

256fS or 384fS system clock. The DAC contains a 3rdorder

DS modulator, a digital interpolation filter, and

an analog output amplifier. The PCM1725 accepts

16-bit input data in either normal or I2S formats.

The digital filter performs an 8X interpolation function

and includes de-emphasis at 44.1kHz. The PCM1725

can accept digital audio sampling frequencies from

16kHz to 96kHz, always at 8X oversampling.

The PCM1725 is ideal for low-cost, CD-quality consumer

audio applications.
