Note: 10 pF load includes parasitic capacitance.
FIGURE 3. Test Circuit (One Channel)
Figure 3 shows a typical test circuit for evaluation of the LM2450. This circuit is designed to allow testing of the LM2450 in a 50Ω
environment without the use of an expensive FET probe. The two 4990Ω resistors form a 400:1 divider with the 50Ω resistor and
the oscilloscope. A test point is included for easy use of an oscilloscope probe. The compensation capacitor is used to
compensate the network to achieve flat frequency response.
