Hi Nick,

thanks for your answer.

I do not understand. I thought these diagrams are showing internal components.

I have attachet the shematic out of the the datasheet.

Could you please mark where the diode and the 2kOhm resistor is?

Thanks a lot.

Thanks.

Klaus.

Hi Klaus,

That schematic is using a 10k res instead of 2k

Hope this clears things up,
