DESCRIPTION
The DF1700 is a high performance, 8x oversampling
CMOS digital filter. This filter accepts 16-bit input
data and is user-selectable for 16-, 18-, or 20-bit
output data. The 8x oversampling feature converts the
input data frequency (fs) to an output data frequency
of 8 x fs by digital interpolation. By providing 8x
oversampled data to an audio DAC, lower order ana-
log filters can be used at the DAC's output, thus
reducing filter phase non-linearities. Oversampling
with the DF1700 simultaneously improves the fidelity of
the analog reconstruction and reduces analog filter
complexity at the output of the DAC.
The DF1700 is available in a plastic 28-pin DIP and a
40-pin SOIC package, and is designed for compatibility
with the Burr-Brown PCM1700 and PCM63 digitalto-
analog converters.
