PCM1700U
PCM1700P
Dual 18-Bit Monolithic Audio
DIGITAL-TO-ANALOG CONVERTER
FEATURES
DESCRIPTION
● DUAL 18-BIT LOW-POWER MONOLITHIC
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.
AUDIO D/A CONVERTER
● VERY LOW MAX THD+N: –92dB Without
External Adjust
● CO-PHASE, LOW-GLITCH ±3V OR ±670µA
AUDIO OUTPUTS
● CAPABLE OF 16X PER CHANNEL
OVERSAMPLING RATE
● COMPLETE WITH INTERNAL
REFERENCE
● SERIAL INPUT FORMAT 100% COMPAT-
IBLE WITH INDUSTRY STD PCM56P
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.
