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 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 .
