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 (R_D) 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 (R_D) of 10 Ω.
