Hi,
I would like to know what impedance the OFFSET pin can seen from the external voltage source?
If you don't have an exact figure, it will also good if you share the maximum possible current that OFFSET pin can sink from the external supply?
Regards,
Deven
Hello Deven,
We do not have a specification for the impedance as it is part of the feedback network. We recommend a source of less than 10Ω output impedance so that the voltage drop across that voltage is not significant to cause a voltage drop not due to the fact that there is a large current required. I simulated it and saw about 25µA at 5V and 12.5µA at 2.5V.
