DESCRIPTION
The PCM1700 is a low cost, high-performance, dual
18-bit digital-to-analog converter. The PCM1700 fea-
tures low glitch, co-phase current and voltage outputs
and only requires
±5V
supplies. The PCM1700 comes
complete with an internal reference and optional MSB
adjustability for even greater THD performance. Total
power dissipation is less than 400mW max. Low
maximum Total Harmonic Distortion + Noise (–92dB
max; PCM1700P-K) is 100% tested. The very fast
PCM1700 is also capable of 16X oversampling rates
on both channels simultaneously, providing freedom
in output filter selection.
The PCM1700 comes in space-saving 28-pin plastic
DIP and SOIC packages. PCM1700 accepts a serial
data input format that is compatible with other Burr-
Brown PCM products such as the industry standard
PCM56P.
