(1) While the input range is 36 V, the full-scale range of the ADC scaling is 40.96 V. See the Basic ADC Functions section. Do not apply
more than 36 V.
(2) RTI = Referred-to-input.
(3) Input leakage is positive (current flowing into the pin) for the conditions shown at the top of this table. Negative leakage currents can
occur under different input conditions.
(4) SMBus timeout in the INA226 resets the interface any time SCL is low for more than 28 ms.
