The CNF0, CNF1, and OUTI4/0 hardware inputs deter-
mine whether the hardware or software controls the
MAX5661 DAC outputs (see Table 13). The CNF0 and
CNF1 inputs enable and disable the DAC outputs or
allow software control of the outputs (see Table 14).
The OUTI4/0 input sets the current range of the OUTI
output. Hardware inputs take precedence over the soft-
ware commands.

zero state and all register bits are set to 0. The zero
state of the voltage output (OUTV) is 0V. The zero state
of the current output (OUTI) is 0mA when OUTI4/0 =
AGND or 4mA when OUTI4/0 = V
CNF1, CNF0:
00 = both outputs disabled
01 = OUTI active, set to 0 to 20mA range
10 = OUTV active, set to bipolar mode
11 = outputs controlled by serial interface

Set the OUTI4/0EN bit to 0 (default power-up state) to
enable the OUTI4/0 hardware input. Set to 1 to disable the
OUTI4/0 hardware input.
When the CNF1 and CNF0 hardware inputs are high, the
OUTION and OUTVON bits control the DAC output OUTI
and OUTV settings.
OUTVON, OUTION:
00 = both outputs powered down
01 = OUTI active
10 = OUTV active
11 = both outputs powered down
Set B/U to 0 to set the OUTV output to bipolar mode
(±10.48V). Set B/U to 1 to set the OUTV output to unipolar
mode (0 to +10.48V).
Set I4TO20BIT to 0 to set the OUTI current range from 0 to
20mA. Set I4TO20BIT to 1 to set the OUTI current range
from 4–20mA.
