Reference Input Voltage Low. Sets minimum out-
put voltage for the DAC.
Not Internally Connected
Reference Input Voltage High. Sets maximum
output voltage for the DAC.
Negative Analog Supply Voltage, 0V or –5V
nominal.
Ground
Positive Power Supply
DAC Voltage Output
The selected DAC register becomes transparent
when LOADDAC is LOW. It is in the latched state
when LOADDAC is HIGH.
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.
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
.
Chip Select. Active LOW.
Enabled by CS. Controls data read and write from
the input register.
