LM2476 Test Circuits
Figure 4 shows a typical test circuit to evaluate the LM2476 CRT Driver and Bias Clamp electrical characteristics. The driver test
circuit is designed to allow for testing the transient response in a 50
environment without the use of an expensive FET probe.
An input from a 50
pulse generator output can be AC coupled and biased with an external supply via the V
BIAS input. The two
2.49 k
resistors form a 200:1 divider with the 50 resistor and the oscilloscope. The clamp test circuit is designed to allow for
testing the clamp outputs. A clamp input can be biased with an external supply via the V
DC input and a high impedance voltmeter
(>100M
) can be used to measure the DC voltage at the clamp outputs. Test points can included to accommodate voltmeter or
oscilloscope probes.

Note: 8 pF load includes parasitic capacitance.
