Hi,

There is no minimum specified value for the RPD resistance. Most of the change will happen over temperature. Here is typical data collected on 2 units to show this effect:

                   RPD (Ohms)
Temp (C)   Unit 1   Unit 2
-40             130      133
25                144      147
85                156      159

Thank you for your reply.

RPD unit is milli ohms?

Hi,

As mentioned before and in the datasheet, RPD Value is in ohms. Since the output capacitance is in the mirco-Farad range, a value in the ohms can discharge fairly quickly.

Is a device with higher or lower RPD needed for timing reasons?
