This output swing performance shown Figure 3-1, where output MCP601 configured gain +2V/V over driven with 40kHz triangle wave. this figure, degradation output swing linearity clearly illustrated. This degradation occurs after point which open loop gain amplifier specified before amplifier reaches maximum minimum output swing.

FIGURE 3-5: Amplifier circuits that used when driving heavy capacitive loads. amplifier required drive larger capacitive loads, circuit shown Figure used. small series resistor (RISO) output amplifier improves phase margin when driving large capacitive loads. This resistor decouples capacitive load from amplifier introducing zero transfer function.

Capacitive Load Stability
Driving capacitive loads cause stability problems with many higher speed amplifiers. closed loop amplifier circuit, good rule thumb design phase margin that less than 45°. This conservative theoretical value, however, phase margin lower, layout parasitics degrade phase margin further causing truly unstable circuit. system phase shift will have overshoot step response approximately 25%. buffer configuration with capacitive load most difficult configuration amplifier maintain stability.
