SAMPLE
, unless otherwise
noted.
Typical values apply for V
DD
= 5V, T
A
= +25°C, unless otherwise noted.
PARAMETER SYM MIN TYP MAX UNITS CONDITIONS
Note 1: This parameter is established by characterization and not 100% tested.
2: The sample cap will eventually lose charge, especially at elevated temperatures, therefore f
CLK
10 kHz for
temperatures at or above 70°C.
