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.

AC Test Circuit
Figure 2 shows a typical test circuit for evaluation of the LM2435. This circuit is designed to allow testing of the LM2435 in a 50
environment without the use of an expensive FET probe. The two 2490
resistors at the output form a 200:1 voltage divider when
connected to a 50
load. The compensation cap is used to flatten the frequency response of the 200:1 divider.

Note:
8 pF load includes parasitic capacitance.
