Hi,

I would like to use ADA4870.

So, I have a question. Please help me.

 

Question:

The ADA4870 is an opamp that can drive an output of 1A.

I checked the output characteristic specification of the data sheet.

Output Current Drive is 1A (typ) and Short-Circuit Protection Current Limit is 1.2 A (typ).

 

Could you tell me the max value of the two specifications?

Experiment has confirmed that it can output about 2A at the peak when driven at high slew rate.

I understand that it can not be recommended as usage,

but please let me know the max value that can be guaranteed as a manufacturer.

 

Data sheet have not written min value and max value, so it will be appreciated if you can tell me.

 

Best Regards,

Naohisa.
