The RM48L950 datasheet shows the following figure regarding the MibADC. It seems, according to the figure, that 39 times the value of IAIL would be consumed by the analog channel that is being sampled. The maximum value of IAIL from the datasheet is 1uA. This would indicate that a maximum of 39uA would be possible. If this is multiplied by the maximum mux resistance of 250 ohms, this would result in a voltage drop of 9.75mV. Assuming a 12-bit ADC and a reference voltage of 4.096V, this would result in an error of 0.25% all by itself (multiple LSBs), not even taking into account the external resistance. This seems excessive. Am I hopefully interpreting this figure incorrectly?
