Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2:
Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may
change when the device is not operated under the listed test conditions.
Note 3:
All voltages are measured with respect to GND, unless otherwise specified.
Note 4:
Calculated value from Voltage Gain test on each channel.
Note 5:
Linearity Error is the variation in dc gain from V
