Other Parts Discussed in Thread: STRIKE
Hello everyone, and happy new year!
So, in relation to this topic, I would like to make more or less the following schematic same ESD protection circuit (TVS + Ferrite Bead + Schottky diodes).
- The power supply of my AOP is V+=12V and V-=GND
- Output voltage = 10V
- Same ESD protection circuit as mentionned (TVS + Ferrite Bead + Schottky diodes)
- Important: The load on the AOP needs to draw up to 20mA (which is covered by the LMH6643)
I am still not sure about the current limiting resistor which is placed between the AOP output and the schottky diodes. The value of this resistor, in order to be under 10mA on the output pin, would limit the current that the load needs.
Do I have to limit this current, or is it sure that the AOP can resist a surge of current that would occur during the ESD tests?
Thank you!
