ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING GUIDELINES
ELECTRICAL CHARACTERISTICS—Dual Supplies
(V+ = +15V, V- = -15V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 3)
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.

FAULT PROTECTION
Note 1: The AOUT pin is not fault protected. Signals on AOUT exceeding V+ or V- are clamped by internal diodes. Limit forward
diode current to maximum current rating.
Note 2: The AIN pin is fault protected. Signals on AIN exceeding -36V to +36V may damage the device. These limits apply with
power applied to V+ or V-, or ±40V with V+ = V- = 0.
