Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
10Hz noise voltage density is sample tested on every lot. Devices may cause permanent damage to the device. Exposure to any Absolute 100% tested at 10Hz are available on request. Maximum Rating condition for extended periods may affect device
Note 6:
Current noise is defined and measured with balanced source reliability and lifetime. resistors. The resultant voltage noise (after subtracting the resistor noise
Note 2:
Input offset voltage measurements are performed by automatic on an RMS basis) is divided by the sum of the two source resistors to test equipment approximately 0.5 seconds after application of power. In obtain current noise. Maximum 10Hz current noise can be inferred from addition, at TA = 25°C, offset voltage is measured with the chip heated 100% testing at 1kHz. to approximately 55°C to account for the chip temperature rise when the
Note 7:
Gain-bandwidth product is not tested. It is guaranteed by design device is fully warmed up. and by inference from the slew rate measurement.
Note 3:
Long-term input offset voltage stability refers to the average trend

This parameter is not 100% tested. line of Offset Voltage vs Time over extended periods after the first 30 days
Note 9:
The inputs are protected by back-to-back diodes. Current-limiting of operation. Excluding the initial hour of operation, changes in VOS during resistors are not used in order to achieve low noise. If differential input the first 30 days are typically 2.5µV. voltage exceeds ±1.8V, the input current should be limited to 25mA.
