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 3rd-
order ∆Σ 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 con-
sumer audio applications.
