AC Test Circuit

Figure 3 shows a typical test circuit for evaluation of the LM2426TE. This circuit is designed to allow testing of the LM2426TE in

a50

Ω 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.
