NIPPON PRECISION CIRCUITS—29
TYPICAL APPLICATION (2)
This circuit shows a basic connection to a 24-bit
input DAC (Burr-Brown PCM1704U).
36.864 MHz external clock, 48/96/192 kHz sam-
pling rate fs, 24-bit data, 8fs or 4fs oversampling
operation (Note that certain circuit details required
for good DAC analog output characteristics have
been omitted.)
