1.8
The DAC output is a differential current type. A termination resistor should be used appropriate for
the maximum allowable output swing. A power down control places the analog circuitry in a low
power state, switching off the current output drive and reference circuitry. When power down mode
is selected the device enters its reset state setting the input data code to +1/2 in 2’s complement or
0 in unsigned binary. Note that neither IOUT or IOUTB can output zero current.
1.8.1
From the voltage reference a control loop defines the current through an external resistor, Rref,
where the current in the reference resistor is 4 times the internal segment current, and the full scale
output current is defined as,
therefore,
