Cautions (HD29026A only)

The short output rise and fall time, as well as the large output amplitude of this product tends to generate overshooting

and undershooting. The connection of 5 to 15 Ω damping resistance (RD) to the output as illustrated in figure 2 serves

to increase the output rise and fall time, making it possible to reduce the chance of overshooting and undershooting.

Figure 3 shows the characteristics that result for a damping resistance (RD) of 10 Ω.
