DESCRIPTION

The PCM1744 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 PCM1744 accepts

24-bit input data in a I2S format.

The digital filter performs an 8x interpolation function

and includes de-emphasis at 44.1kHz. The PCM1744

can accept digital audio sampling frequencies from

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

The PCM1744 is ideal for low-cost, CD-quality consumer

audio applications.
