Supply and Channel Filtering<br />
►VDD and VSS bypassed with<br />
100nF close to MCU<br />
►“<strong>Analog</strong>” power and ground<br />
isolated from “digital” power<br />
and ground<br />
►Tip - place channel filter cap<br />
close to MCU<br />
►Tip - place channel resistor<br />
close to source<br />
►Tip - for off-board inputs,<br />
physically place resistors in<br />
parallel so that noise does not<br />
couple to filtered nodes<br />
