Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
Input Offset Voltage measurements are performed by automatic
test equipment approximately 0.5 sec after application of power.
Note 3:
Current noise is defined and measured with balanced source
resistors. The resultant voltage noise (after subtracting the resistor noise
on an RMS basis) is divided by the sum of the two source resistors to
obtain current noise.
Note 4:
Gain-bandwidth product is not tested. It is guaranteed by design
and by inference from the slew rate measurement.
Note 5:
The inputs are protected by back-to-back diodes. Current limiting
resistors are not used in order to achieve low noise. If differential input
voltage exceeds
±1.8V,
the input current should be limited to 25mA.
