Note 1: The amplifier inputs are connected by internal back-to-back clamp diodes. In order to minimize noise in the input stage,
current-limiting resistors are not used. If differential input voltages exceeding 1V are applied, limit input current to 2ꢂmA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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.
