DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
CLK
5
I
Serial interface clock. The input digital data is shifted into the serial interface register on the falling edge of the clock
applied to the CLK terminal.
DACA

DAC A analog output
DACB

DAC H analog output
DATA
4
I
Serial interface digital data input. The digital code for the DAC is clocked into the serial interface register serially.
Each data bit is clocked into the register on the falling edge of the clock signal.
GND
3
I
Ground return and reference terminal
LDAC
13
I
Load DAC. When LDAC is high, no DAC output updates occur when the input digital data is read into the serial
interface. The DAC outputs are only updated when LDAC is taken from high to low.
LOAD
12
I
Serial interface load control. When LDAC is low, the falling edge of the LOAD signal latches the digital data into
the output latch and immediately produces the analog voltage at the DAC output terminal.
REF1
14
I
Reference voltage input to DAC A
BCD. This voltage defines the analog output range.
REF2
11
I
Reference voltage input to DAC E
FGH. This voltage defines the analog output range.
VDD
6
I
Positive supply voltage
