CAUTION: Damage can occur to the Allegro CX or NI DAQCard if
these constraints are not followed.
The output voltage must be between 0 and + 4.8V. Setting a
negative voltage may damage the DAQ Expansion Pod excitation
circuit.
Voltages too near supply rails (over 4.8V) will result in digital
noise that adversely affects sensors.
Output current is limited to a maximum of 200mA.
