SCLK
Serial Clock Input
Serial Data Output. Open-drain N-channel MOSFET output: requires external pull-up resis-
tor. Data on DOUT changes on the falling edge of SCLK. Serial output data is delayed 24
clock cycles from DIN.
Serial Data Input. CMOS- and TTL-compatible input. Data is clocked into DIN on the rising
edge of SCLK.
CS
must be low for data to be clocked in.
Chip-Select Input, active low. Data is shifted in and out when
CS
is low. DAC latches are
updated when
CS
is high and
LDAC
is low.
