The PA91 is a 450 V power operational amplifier that exhibits a low 10 mA of quiescent current and is designed as a low-cost solution for driving continuous output currents up to 200 mA and pulse currents up to 350 mA 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.
