FEATURES
DESCRIPTION
q SAMPLING FREQUENCY (fS): 16kHz to 96kHz
The PCM1704 is a precision, 24-bit digital-to-analog
converter with exceptionally high dynamic performance. The ultra-low distortion and excellent lowlevel signal performance makes the PCM1704 an ideal
candidate for high-end consumer and professional
audio applications. When used with a digital interpolation filter, the PCM1704 supports 8X oversampling
at 96kHz.

The PCM1704 incorporates a BiCMOS sign-magnitude architecture that eliminates glitches and other
nonlinearities around bipolar zero. The PCM1704 is
precision laser-trimmed at the factory to minimize
differential linearity and gain errors.
In addition to high performance audio systems, the
PCM1704 is well-suited to waveform synthesis applications requiring very low distortion and noise.
