My low-pass filter on each channel has a 1k resistor. I didn't see anything in the datasheet for the Sharp range sensor's output impedance. Do you have any suggestions how long I should wait for the input voltage to settle? I will try moving the MUX switch code to allow for settling time as well. Thanks. Craig
