(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating
conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages are with respect to GND. Currents are positive into, negative out of the specified terminal.
ELECTRICAL CHARACTERISTICS
V_DD = 12 V, 4.7-µF capacitor from V_DD to GND, 0.22µF from 3V3 to AGND, T_A = T_J = -40°C to 105°C, (unless otherwise
noted).
