DESCRIPTION
The PCM1794A 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 PCM1794A
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.
