INA186: Ref-Resistor

Part Number: INA186

Hi Expert,

could you please tell me the value of the internal resistors in the REF-Pin.

I want to supply the REF-Pin with 2.5V, so I am using a voltage divider with two 10K resistors.

Howcver, ther is an internal serial resistors. Could this affect th 2.5V?

Best regards

Mahmoud

    Hi Mahmoud, 

    This is not information that we share. But the internal resistors are big enough where they draw very little current. Your voltage divider resistance values should not cause an issue.

    Best,
