Hi Lars, thank you for your detailed reply, I found this reference design TIDA-01333 ( www.ti.com/.../TIDA-01333 ) which I think should be more suitable for my application. I just have 2 questions: Firstly, is it possible to implement the open wire detection using only a 2Mohm resistor pulled up to 13V before the MUX? And secondly, I am not quite sure how the C44 100pF capacitor were chosen, as it was not mentioned in the design guide. Best regards, Jonas
