INA146: Tolerance of Internal Resistors

Hi Jejomar,

Do we have a concluded information on what is the tolerance of the internal resistors of INA146?

The INA146's internal resistor matching should be approx. 0.01% or 100ppm range or better (50ppm) at room temperature, see the captured image below

Enclosed is an article that talks about the topics.

If you have additional questions, please let us know.
