NOTE:
1. The LBO pin will be internally pulled to V
DD if it is not actively driven in the application and the ZZ pin will be internally pulled to VSS if not actively driven.
NOTES:
1. All values are maximum guaranteed values.
2. At f = fMAX, inputs are cycling at the maximum frequency of read cycles of 1/tCYC while ADSC = LOW; f=0 means no input lines are changing.
