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 Willie,
I have attached accuracy analysis document for our circuit based on CN0287. Only major change with respect to CN0287 is that we have changed our reference voltage to 2.5V (We are planning to use ADR3425 instead of ADR3440). This change…
