Note: 10pF load includes parasitic capacitance.
FIGURE 3. Test Circuit
Figure 3 shows a typical test circuit for evaluation of the LM2432. This circuit was designed to test the transient response of the
LM2432 in a 50Ω environment without the use of an expensive FET probe. On the input side, a 50Ω pulse generator output can
be AC coupled and biased with an external supply via the V
input. On the output side, the two 4990Ω resistors form a 400:1
ADJ
divider with the 50Ω resistor and the oscilloscope. A test point can be included for easy use of an oscilloscope probe. A
compensation capacitor can be used to compensate the network to achieve a flat frequency response.
