OPA2320: Shutdown pin current

Mark Guastaferro

Part Number: OPA2320

Tool/software:

What is the max input bias current on the Shutdown pin(s) across temp when the SHDN pin is pulled high? The data sheet only provides the typical current at 25C. (0.13 uA). This data is needed for a system stress analysis.

Mark,

I have no specific data, but just using 10X or 1.3uA or even 100 X 13uA likely wouldn't affect the system in a meaningful way.

Thanks Ron,

The customer is trying to make sure they capture all the power dissipation and that power supplies have margin for worst case conditions for all components on the board.

If I told them that we assume the max current would be below 10x of the typical, (1.3uA), would that be a reasonable assumption?

Mark,

Very reasonable.
