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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(V_CC = CPV_CC = +3.0V, T_A = +25°C, C1 = C2 = 1µF, C3 = C4 = C5 = 0.1µF, load at OUT1–OUT5 = 150Ω to GND, R_BIAS = 100kΩ to
GND, unless otherwise noted. See the Functional Diagram/Typical Application Circuit.)
