APPLICATION INFORMATION

driving a capacitive load

When the amplifier is configured in this manner, capacitive loading directly on the output decreases the device’s

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

in Figure 25. A minimum value of 20

Ω should work well for most applications.
