• Description: Monolithic Triple 4 Ns Crt Driver
• Manufacturer: National Semiconductor Corporation

AC Test Circuit
DS200128-3
Note: 8 pF load includes parasitic capacitance.
FIGURE 2. Test Circuit (One Channel)
Figure 2 shows a typical test circuit for evaluation of the LM2463. This circuit is designed to allow testing of the LM2463 in a 50
environment without the use of an expensive FET probe. The two 2490 resistors form a 200:1 divider with the 50 resistor and
the oscilloscope. A test point is included for easy use of an oscilloscope probe.The compensation capacitor is used to
compensate the stray capacitance of the two 2490
resistors to achieve flat frequency response.
