REFH (Pins 3, 4):
ADC High Reference. Short together and
bypass to pins 5, 6 with a 0.1
μ
F ceramic chip capacitor as
close to the pin as possible. Also bypass to pins 5, 6 with
an additional 2.2
μ
F ceramic chip capacitor and to ground
with a 1

F ceramic chip capacitor.
REFL (Pins 5, 6):
ADC Low Reference. Short together and
bypass to pins 3, 4 with a 0.1
μ
F ceramic chip capacitor as
close to the pin as possible. Also bypass to pins 3, 4 with
an additional 2.2
