• Description: 220v Monolithic Triple Channel 10 Mhz Crt Dtv Driver
• Manufacturer: National Semiconductor Corporation

AC Test Circuit
Note: 10 pF load includes parasitic capacitance.
Figure 3 shows a typical test circuit for evaluation of the LM2425. This circuit is designed to allow testing of the LM2425 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 a flat frequency response.
