Description:
|
Operational amplifiers (op amps) that drive large capacitive loads tend to have peaking and oscillation problems when they are not properly compensated.
Other problems include: reduced bandwidth, lower output slew rate, and higher power consumption. This application note explains why these problems occur, how to modify the op amp circuit for better performance, and how to quickly compute circuit values.
