(1)

Although 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.

7.5 Electrical Characteristics

at TA = 25°C, VS = 3.3 V, VIN+ = 12 V, VSENSE = (VIN+ – VIN–) = 0 mV and VVBUS = 12 V (unless otherwise noted)
