Tab. 3: Table of Vset / Vout and Vmon / Vout coefficent
Example A7502P: if Vset = 2 V, then HV Output = 1648 V ± 8 V
Example A7502P: if Vmon = 1.5 V, then HV Output = 1236 V ± 5 V

Tab. 4: Table of Iset / Imax out and Imon / Iout coefficent
(*) Iset and Imon expressed in V, Imax out and Iout expressed in µA.
N.B.: In parallel to the load we have a 300 MΩ resistor for the voltage
feedback; therefore the Imon current with load ∞ is Vout/300MΩ
Example A7502P: if Iset = 2 V, then Imax out = 90 µA ± 22 µA
Example A7502P: if Imon = 1 V, then Iout = 45 µA ± 18 µA
