DESCRIPTION

The PCM1744 is a complete low cost stereo audio

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

256f

or 384f

system clock. The DAC contains a 3rd-

order

鈭單?/div>

modulator, a digital interpolation filter, and

an analog output amplifier. The PCM1744 accepts

24-bit input data in a I

S 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 con-

sumer audio applications.
