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

FIGURE 2 Test Circuit (One Channel)
Figure 2
shows a typical test circuit for evaluation of the
LM2408 This circuit is designed to allow testing of the
LM2408 in a 50X environment such as a pulse generator
oscilloscope or network analyzer The 4950X resistor at the
output forms a 100 1 voltage divider when connected to a
50X load
