OPA549-HIREL: Current limit Tolerance & Offset.

Louis Han15

Part Number: OPA549-HIREL
Other Parts Discussed in Thread: OPA549

Hello

We designed the following conditions using OPA549-HIREL.
The Design is complete and OPA549-HIREL can not be changed.

Supply Voltage: +/-15V

Desire Output Current: +/-1A, +/-0.33A

Current Limit: +/-0.47A, +/-1.45A

We request current limit Tolerance & Offset when current limit is 0.47A and 1.45A.
What is the Tolerance range below 1A?

Best Regards

    Hello Louis,

    As with the standard OPA549 product, no additional assurances are provided regarding the output current limit tolerance parameter beyond what is what is listed in the OPA549-HIREL Electrical Characteristics table. Therefore, please refer to my previous reply about the OPA549 output current limit tolerance:

    https://e2e.ti.com/support/amplifiers/f/14/t/885659

    Do notice that the OPA549-HIREL output current limit tolerance maximum is a little higher than that specified for the standard OPA549.

    Regards, Thomas
