VREF = 5 V, unless otherwise noted.
The offset DAC setting has no effect on the output voltage range.
Do not allow the MEASOUT output range to exceed the AIN range of the ADC.
For the purposes of sharing ADCs among multiple DPS channels, note that the multiplexer is not absolutely necessary because the AD5560 MEASOUT path has a
tristate mode.
