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.
