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.
Asynchronous Load DAC Input, active low. DAC latches are updated when CS is high and
LDAC is low.
Positive Supply Voltage
