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
GND unless otherwise specified
Note 3: I
Note 4: The equivalent charge of an LSB in the accumulated charge
registers (C,D) depends on the setting of the internal pre-scaling factor M.
It is calculated by:
