DESCRIPTION
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.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
