Stereo Audio
DIGITAL-TO-ANALOG CONVERTER
16 Bits, 96kHz Sampling
TM
PCM1725
DESCRIPTION
The PCM1725 is a complete low cost stereo audio
digital-to-analog converter (DAC), operating off of a
256f
S
or 384f
S
system clock. The DAC contains a 3rd-
order
Σ
modulator, a digital interpolation filter, and
an analog output amplifier. The PCM1725 accepts
16-bit input data in either normal or I
2
S 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 con-
sumer audio applications.
