With the POV function the overhead voltage can be increased. If the POV pin is left open
the overhead voltage is internally set to 1.1

has to be recalculated if the PTG is shorted.
Please note that the maximum signal current at the two-wire side can not be higher than
9 mA.
How to use POV:
1. Decide what overhead voltage (

If the overhead voltage exceeds 3.2
by connecting pin PTG to AGND. Please note, that the 2-wire impedance,
4-wire to 4-wire gain has to be recalculated.
