The PA91 is a 450V power operational amplifier that exhibits a low 10mA of quiescent current and is designed as a low-cost solution for driving continuous output currents up to 200mA and pulse currents up to 350mA in high voltage applications including instrumentation, piezoelectric transducers and electrostatic transducers and deflection. External compensation with the PA91 provides flexibility in choosing bandwidth and slew rate for the application. Housed in a space saving, electrically isolated 12-pin PowerSIP package, the PA91 lends itself to high density circuit board layouts.
