APPLICATION INFORMATION

driving a capacitive load

When the amplifier is configured in this manner, capacitive loading directly on the output will decrease the

device’s phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater

shown in Figure 42. A minimum value of 20

Ω should work well for most applications.
