High Capacitance Line Driver

Description

Capacitive loads invite amplifier instability by reducing phase margin. Instability can be prevented by isolating the load capacitance from the amplifier output by a small resistor R3. To eliminate a voltage drop error when current is drawn through that resistor, DC feedback is sensed on the load side of R3. High- frequency feedback is provided by C2.
