Note 12: Programming time does not include overhead associated with the utility ROM interface.
Note 13: V

= AV

DD

.

Note 14: The operational input voltage range for each individual input of a differentially configured pair is from GND to AVDD. The

operational input voltage difference is from -V

REF

/2 to +V

REF

/2.

Note 15: The typical value is applied when a conversion is requested with ADPMO = 0. Under these conditions, the minimum delay

is met. If ADPMO = 1, the user is responsible for ensuring the 4µs delay time is met.

Note 16: Switching ADC reference from either internal or external reference to AVDD. Sample accuracy is not guaranteed prior to

ADC reference settlement.

Note 17: Total on-board decoupling capacitance on the AVDD pin < 100nF. The output impedance of the regulator driving the

AVDD pin < 10

Ω.

Note 18: This parameter is guaranteed by design and is not production tested.
