The supply Voltage for the output driver U(dr) of the BBI 22998 = UB
U(dr) = UB

The Voltage drop across the output driver is:
~2.5V
Calculation of the max. Resistance connected to the analog current output:
R <= (U(dr) – 2.5V) / I
Example:
UB = 12V => U(dr) = 12V
R <= (12V – 2,5V) / 0.02A
R <= 475 Ohm
UB = 24V => U(dr) = 24V
R <= (24V – 2,5V) / 0.02A
R <= 1075 Ohm
