OPA547EVM: OPA547EVM

Part Number: OPA547EVM
Other Parts Discussed in Thread: OPA547

following my previous request , i d like to drive current between 10 to 200 mA to heat up in AC a few ohm resistor. thanks

  • Hello Ahmed,

    Certainly, the OPA547 is capable of delivering that level of current. However, do note that the Improved Howland Current Pump will have to be designed for a specific peak to peak output current range. You will be able to reduce that peak to peak current level if needed by backing off on the input voltage drive.

    It would be best if we keep our OPA547 discussion to one e2e inquiry. Therefore, if you can close this inquiry we can keep our discussions to your other OPA547 e2e inquiry. That would be helpful for our tracking here at TI.

    Thanks, Thomas
