DESCRIPTION
The PCM58P is a complete, precision 18-bit digital-
to-analog converter with ultra-low distortion over a very
wide frequency range. The latched serial input data
format of the PCM58P is totally based on the widely
successful 16-bit PCM56P format (with the addition of
two more data bits). The PCM58P features a very low
noise and fast settling current output.
The PCM58P comes in a 28-pin plastic DIP package.
A provision is made for external adjustment of the four
MSBs to further improve the PCM58P’s specifications,
if desired. Applications include very low distortion
frequency synthesis and high-end consumer and pro-
fessional digital audio applications.
