PIN LABEL DESCRIPTION
1V
DD
Positive Analog Supply Voltage, +5V nominal.
2V
OUTD
DAC D Voltage Output
3V
OUTC
DAC C Voltage Output
4V
REFL
Reference Input Voltage Low. Sets minimum out-
put voltage for all DACs.
5V
REFH
Reference Input Voltage High. Sets maximum out-
put voltage for all DACs.
6V
OUTB
DAC B Voltage Output
7V
OUTA
DAC A Voltage Output
8V
SS
Negative Analog Supply Voltage, 0V or –5V nomi-
nal.
9 GND Ground
10 SDI Serial Data Input
11 CLK Serial Data Clock
12 CS Chip Select Input
13 NIC Not Internally Connected.
14 LOADDACS The selected DAC register becomes transparent
when LOADDACS is LOW. It is in the latched state
when LOADDACS is HIGH.
15 RESET Asynchronous Reset Input. Sets all DAC registers
to either zero-scale (000
H
) or mid-scale (800
H
)
when LOW. RESETSEL determines which code is
active.
16 RESETSEL When LOW, a LOW on RESET will cause all DAC
registers to be set to code 000
H
. When RESETSEL
is HIGH, a LOW on RESET will set the registers to
code 800
H
.
