Note 1:
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2:
All voltages are measured with respect to GND, unless otherwise specified.
Note 3:
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 4:
Calculated value from voltage gain test on each channel.
Note 5:
Linearity error is the variation in DC gain from V

AC Test Circuit
Figure 2 shows a typical test circuit for evaluation of the
LM2402. This circuit is designed for testing the LM2402 with
a FET probe. When calculating the total load capacitance,
the Tektronix P6201 FET probe with a 100:1 divider is speci-
fied to have 1.5 pF. The total board capacitance should be
6.5 pF.
