2. ADC accuracy vs. negative injection current: Injecting a negative current on any analog input pins should

be avoided as this significantly reduces the accuracy of the conversion being performed on another analog

input. It is recommended to add a Schottky diode (pin to ground) to analog pins which may potentially inject

negative currents.

Any positive injection current

affect the ADC accuracy.

General PCB design guidelines

Power supply decoupling should be performed as shown in Figure 9. The 10 nF capacitor

should be ceramic (good quality) and it should be placed as close as possible to the chip.
