OTHER APPLICATIONS REQUIRING 24-BIT AUDIO
The PCM1739 is a CMOS, monolithic, integrated circuit which includes stereo 24-bit audio digital-to­analog converters and support circuitry in a small SSOP-28 package. The data converters utilize Burr­Brown’s enhanced multi-level delta-sigma architec­ture, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM1739 accepts industry-standard audio data formats with 16- or 24-bit data, providing easy interfacing to audio DSP and decoder chips. Sampling rates up to 192kHz are supported.

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
ELECTROSTATIC DISCHARGE SENSITIVITY
specifications.
