DESCRIPTION
The DSD1700 is a unique digital-to-analog converter
designed for DSD audio applications. The DSD1700
consists of a single-channel, 8-tap analog FIR filter
constructed using a double differential circuit architecture, ensuring excellent dynamic performance and
high power- supply noise rejection. The DSD1700
also includes the necessary logic required to interface
directly to a DSD decoder IC.
The overall features and performance of the DSD1700
make it an ideal choice for high-performance Super
Audio CD players and DSD studio applications.

PIN CONFIGURATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
