Hi Anders, Reply from the Systems Team: "I would expect the sigma-delta ADC to clip because the op-amps in the modulator don't have the headroom to support such a high reference voltage. So probably the customer is not using the sigma-delta but the ADC10" The SD24_B is simply not capable of converting the full-scale 3.3 V and clipping should be expected, there should be no damage to the physical pin since it can be used as the ADC10 reference but I don't know if the same can be said for the SD24_B op-amps. Since this issue was not discovered during development, and given that the entirety of our SD24_B resources revolve around a voltage reference of ~1.2-1.5 V, it is once again theorized that the customer is actually using the ADC10 peripheral. Can they provide a small code project that proves otherwise and demonstrates full-scale Vref functionality with the SD24_B? Regards, Ryan
