PA15FL PA15FLA RoHS High Voltage Power Operational Amplifiers COMPLIANT FEATURES High Voltage 450V (225V) Low Cost Low Quiescent Current 3mA max High Output Current 200mA Programmable Current Limit APPLICATIONS Piezoelectric Positioning High Voltage Instrumentation Electrostatic Transducers Programmable Power Supplies Up To 440V DESCRIPTION The PA15FL is a high voltage, low quiescent current MOSFET operational amplifier designed as a low cost solution for driving continuous output currents up to 200mA and pulse currents up to 350mA into capacitive loads. The safe operating area (SOA) has no second breakdown limitations and can be observed for all type loads by choosing an appropriate current limiting resistor. The MOSFET input stage has integrated static and differential mode protection. The MOSFET output stage is biased AB for linear operation. External compensa tion provides flexibility in choosing bandwidth and slew rate for the application. The 10 pin power SIP pack age is electrically isolated.
