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
鹵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 (鈥?2dB
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.
