Note 2: All units are 100% production tested at TA = +85°C. Limits over the operating temperature range are guaranteed by design and characterization and are not production tested.
Note 3: ΔRON = RON (MAX) - RON (MIN).
Note 4: Guaranteed by design. Not production tested.
Note 5: Flatness is defined as the difference between the maximum and minimum value of
MAX4888A/MAX4889A
