APPLICATIONS

DESCRIPTION

The PCM1794 is a monolithic CMOS integrated circuit that

includes stereo digital-to-analog converters and support

circuitry in a small 28-lead SSOP package. The data

converters use TI’s advanced segment DAC architecture

to achieve excellent dynamic performance and improved

tolerance to clock jitter. The PCM1794 provides balanced

current outputs, allowing the user to optimize analog

performance externally. Sampling rates up to 200 kHz are

supported.

This integrated circuit can be damaged by ESD. Texas Instruments 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments

semiconductor products and disclaimers thereto appears at the end of this data sheet.
