Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Guaranteed by design and not tested in production.
Note 3: Measured at least 20ms after power on.
Note 4: Tested in feedback loop to SENSE+ and SENSE–.
