13 V
REFL
Reference Input Voltage Low. Sets minimum out-
put voltage for the DAC.
14 NIC Not Internally Connected
15 V
REFH
Reference Input Voltage High. Sets maximum
output voltage for the DAC.
16 V
SS
Negative Analog Supply Voltage, 0V or –5V
nominal.
17 GND Ground
18 V
DD
Positive Power Supply
19 V
OUT
DAC Voltage Output
20 LOADDAC The selected DAC register becomes transparent
when LOADDAC is LOW. It is in the latched state
when LOADDAC is HIGH.
21 RESET Asynchronous Reset Input. Sets the DAC register
to either zero-scale (000
H
) or mid-scale (800
H
)
when LOW. RESETSEL determines which code is
active.
22 RESETSEL When LOW, a LOW on RESET will cause the DAC
register to be set to code 000
H
. When RESETSEL
is HIGH, a LOW on RESET will set the registers to
code 800
H
.
23 CS Chip Select. Active LOW.
24 R/W Enabled by CS. Controls data read and write from
the input register.
