VREFHIA 25 16 16 14 I/O
ADC-A High Reference. In external reference mode,
externally drive the high reference voltage onto this pin. In
internal reference mode, a voltage is driven onto this pin by
the device. In either mode, place at least a 2.2-µF capacitor
on this pin. This capacitor should be placed as close to the
device as possible between the VREFHIA and VREFLOA
pins. Do not load this pin externally in either internal or
external reference mode.
VREFHIB 24 16 16 14 I/O
ADC-B High Reference. In external reference mode,
externally drive the high reference voltage onto this pin. In
internal reference mode, a voltage is driven onto this pin by
the device. In either mode, place at least a 2.2-µF capacitor
on this pin. This capacitor should be placed as close to the
device as possible between the VREFHIB and VREFLOB
pins. Do not load this pin externally in either internal or
external reference mode.
VREFHIC 24 16 16 14 I/O
ADC-C High Reference. In external reference mode,
externally drive the high reference voltage onto this pin. In
internal reference mode, a voltage is driven onto this pin by
the device. In either mode, place at least a 2.2-µF capacitor
on this pin. This capacitor should be placed as close to the
device as possible between the VREFHIC and VREFLOC
pins. Do not load this pin externally in either internal or
external reference mode.
