Note 1: Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur.
Note 2: All voltages are measured with respect to GND, unless otherwise
Note 3: Operating ratings indicate conditions for which the device is func-
tional, 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 per-
formance characteristics may change when the device is not operated under
the listed test conditions.

FIGURE 2. Test Circuit (One Channel)
Figure 2 shows a typical test circuit for evaluation of the LM2403. This circuit is designed to allow testing of the LM2403 in a 50Ω
environment without the use of an expensive FET probe. The 4950Ω resistor at the output forms a 100:1 voltage divider when
connected to a 50Ω load.
