3 Description
(1) For all available packages, see the orderable addendum at
the end of the data sheet.
The PCM510xA devices are a family of monolithic
CMOS-integrated circuits that include a stereo digital-
to-analog converter and additional support circuitry in
a small TSSOP package. The PCM510xA devices
use the latest generation of TI’s advanced segment-
DAC architecture to achieve excellent dynamic
performance and improved tolerance to clock jitter.
