I need a little advice with using external ADC's with lpc processors. Apparently, the reference, analog ground, and input signals looks somewhat distorted (spiky) on the oscilloscope whenever the 16-bit (unipolar) Converter is busy converting. As a result, the readings don't come out as consistent as it should (even when both inputs are grounded). Is there any way to avoid this problem?
