† Stresses above those listed under “Maximum ratings” may
cause permanent damage to the device. This is a stress rating
only and functional operation of the device at those or any
other conditions above those indicated in the operational list-
ings of this specification is not implied. Exposure to maximum
rating conditions for extended periods may affect device reli-
ability.

CHARACTERISTICS
Sample time is the time between conversions after the address byte has been sent to the converter. Refer
to Figure 5-6.
This parameter is periodically sampled and not 100% tested.
