TIMING CHARACTERISTICS
(V
temperature range are guaranteed by design.)
Note 1: The setting in the DAC is guaranteed to remain valid as long as V
Note 2: BATT Operating Range is guaranteed by the Microsecond-Volt Time Constant specification.
Note 3: Current sourced from a pin is denoted as positive current. Current sunk into a pin is denoted as negative current.
Note 4: Guaranteed by design.
