DAC OUTV output enable bit. Set to 1 to enable the OUTV output.
DAC OUTI output enable bit. Set to 1 to enable the OUTI output.
Reserved. Always set to 0.
Voltage-output unipolar/bipolar mode select bit. Set to 0 (default power-up state) to select the
bipolar output range (±10.48V). Set to 1 to select the unipolar output range (0 to +10.48V).
OUTI4/0 enable bit. Set to 0 (default power-up state) to enable the OUTI4/0 hardware input. Set
to 1 to disable the OUTI4/0 hardware input, thereby controlling the current-output range
through software commands.
OUTI current range bit. Set to 0 to set the OUTI current range from 0 to 20mA. Set to 1 to set
the OUTI current range from 4–20mA.
Clear enable bit. Set to 0 to enable the external CLR input. Set to 1 to disable the external CLR
input.
Clear mode bit. Set to 1 and drive the external CLR input low to force the DAC output to the
value stored in the clear register. Set to 0 and drive the external CLR input low to force the DAC
output to 0V in voltage mode or 0mA/4mA depending on output-current mode.
Remain in clear bit. Set to 1 to remain in the clear state. The RCLR bit determines the steps
required to exit the clear state. See the CLR Input section.
Fault output enable. Set to 1 to enable the FAULT output functionality. Set to 0 to disable the
FAULT output functionality. In single supply mode, set to 0 to disable the FAULT pin function.

Output voltage fault bit (read only). The FAULTV bit is set to 1 when FAULT triggers due to an
OUTV short-circuit condition. The FAULTV bit is a don’t-care bit for control-register write
commands. In single supply mode, FAULTV = 1 must be ignored.
Output-current fault bit (read only). The FAULTI bit is set to 1 when FAULT triggers due to an
OUTI open-circuit condition. The FAULTI bit is a don’t-care bit for the control register write
commands. In single supply mode, monitor the FAULTI bit for any FAULTI condition.
