SCLK

Serial Clock Input

Serial Data Output. Open-drain N-channel MOSFET output: requires external pull-up resis-

12

DOUT

tor. Data on DOUT changes on the falling edge of SCLK. Serial output data is delayed 24

clock cycles from DIN.

13

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.

14

CS

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.

15

LDAC

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

LDAC is low.

16

VDD

Positive Supply Voltage
