AC TEST CIRCUIT

Note: 8 pF load includes parasitic capacitance.

Figure 2. Test Circuit (One Channel)

Figure 3 shows a typical test circuit for evaluation of the LM2466. This circuit is designed to allow testing of the

LM2466 in a 50

Ω environment without the use of an expensive FET probe. The two 2490Ω resistors form a

200:1 divider with the 50

Ω 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

Ω resistors to

achieve flat frequency response.
