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:
All currents into pins are positive. All voltages are referenced to
ground, unless otherwise noted.
Note 3:
An internal shunt regulator limits the INTV
CC
pin to a minimum of
5.8V. Driving this pin to voltages beyond 5.8V may damage the part. This
pin can be safely tied to higher voltages through a resistor that limits the
current below 35mA.
Note 4:
Internal clamps limit the SCL and SDAI pins to a minimum of
5.9V. Driving these pins to voltages beyond the clamp may damage the
part. The pins can be safely tied to higher voltages through resistors that
limit the current below 5mA.
Note 5:
Guaranteed by design and not subjected to test.
Note 6:
∆SENSE is defined as V

Note 7:
TUE is the maximum ADC error for any code expressed as a
