3.1
Stresses above the absolute maximum rating may cause permanent damage to
the device. Extended operation at the maximum levels may degrade
performance and affect reliability.
The inputs are protected by back-to-back diodes. Current limiting resistors are
not used in order to achieve low noise performance. If the differential input
voltage exceeds ±1V, the input current should be limited to ±25mA.
