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.

Note 2: EP is the logic ground reference to the SHDN pin.
Note 3: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design.
Note 4: OCMRR is mainly determined by external gain resistors matching. The formula used for OCMRR calculation assumes that
gain resistors are perfectly matched. Therefore, OCMRR = (1 + RF/RG) x ∆VOS/∆V(VOCM).
