TIDA-00639: TIDA-00639

Part Number: TIDA-00639
Other Parts Discussed in Thread: OPA333

Hi all,

the sense resistor needs to be small in comparison to R1 and others of the OPA333 circuitry. But what if I need to increase the sense resistor, if it is needed to measure small load currents?

What would be your proposal?

Thanks and best regards - Stefan

    Hi Stefan,

    In case the current is small, it is possible to scale all the resistors in the circuit by same factor. It will maintain the same ratio between the sense resistor and other resistors.
