NIPPON PRECISION CIRCUITS—28
TYPICAL APPLICATION (1)
This circuit shows a basic connection to a 24-bit
input DAC (SM5865BM).
36.864 MHz external clock, 48/96/192 kHz sam-
pling rate fs, 24-bit data, 8fs oversampling operation
(Note that certain circuit details required for good
DAC analog output characteristics have been omit-
ted.)
