CBM8655-CBM8656

OPERATION INSTRUCTION

With this circuit in place, output swing is maintained, and the amplifier is stable at all gains.

Figure 55 shows the implementation of a snubber, which reduces overshoot by more than 30%

and eliminates ringing. Using a snubber does not recover the loss of bandwidth incurred from a

heavy capacitive load.
