OPA320: S model with shutdown function

Part Number: OPA320

Tool/software:

Dear OP-AMP Technical Support.

When shutting down the OPA320S, is it okay if a signal is still applied to the input.
In the absolute maximum ratings, the input is up to VCC if there is no current limit, but are there any restrictions with the shutdown function?

Best Regards.

Yes

Shutdown turns off the output pin and internal bias generator. With inputs and output within the range of the power supply no input or output current flows.

Hello Ron-san,

Thank you for your technical support.
I understand that even in shutdown the input signal can be applied up to VCC.
And, I understand that even if an input is applied in shutdown mode, the leakage current does not increase.
I will recommend your advice to our customers.

Best Regards.
