Hi Wouter,

     I can see that there is a 100nf capacitor on the ref pin. Can you try changing to larger capacitor value, like 10uf. From your reference circuit, the ADR3440 is the source for the 4.096V and 2.418V reference. right? so the 47k and 82k and…

Hello Suresha N S

For this circuit, we assume customer doing the system calibration to cancel out all the linearity error. Besides that, the non-linearity error (drift, noise) would decide the final accuracy performance. We only tested the circuit under…
