Hi Luca,

Can you please provide more information? What application are you using the part for and what voltage you are using this part at? There is no specific maximum input current rating on the part in the datasheet. I will try to find out more about the internal characteristics of this part.

Thanks!

Hi Kanan,
in my application LMH6703 is in non-inverting configuration with a gain of 4 V/V, and ±5-V power supplies. I'm interested in knowing how to size the resistance in series at the non inverting input for overvoltage protection. I would expect to have a maximum current value around 10 mA for input clamps diodes, isn't it?
many thanks
Luca

Hi Luca,

Yes, you are correct. You should expect to have a maximum current of 10 mA. Also, the thread kai has provided should help you as it is a similar question to yours.

Thanks!
