 PA15 Data Sheet

The PA15FL is a 450V power operational amplifier that exhibits a very low 3mA of quiescent current. This op amp is designed as a low cost solution for driving continuous output currents up to 200mA, and pulse currents up to 350mA, into capacitive loads such as piezoelectric positioning, high voltage instrumentation and electrostatic transducer applications.

The safe operating area (SOA) can be observed for all operating conditions by selection of user programmable current limit resistors. The MOSFET input stage has integrated static and differential mode protection. The MOSFET output stage is biased A/B for linear operation. External compensation provides flexibility in choosing bandwidth and slew rate for the specific application.

The PA15FLA is the A grade version providing enhance performance in the areas of offset voltage, offset current and bias current. The PA15 series is a hybrid product design housed in an electrically isolated 10-pin PowerSIP package. For continuous operation under load, a heatsink of proper rating is recommended.
