PA99 PA99A RoHS Power Operational Amplifier COMPLIANT FEATURES Up to 2400V Output P-P Wide Supply Range - 100V to 1250V Programmable Current Limit 50mA Continuous Output Hermetically Sealed Package Temperature Sensor APPLICATIONS Semiconductor Testing Piezo Positioning High Voltage Instrumentation Electrostatic Deflection DESCRIPTION The PA99 is an ultra-high 2,500 V power operational amplifier designed for output currents up to 50mA to target high voltage applications including piezoelectric positioning, instrumentation, semiconductor pro- duction testing, and electrostatic deflection. Output voltages can swing up to 2,400 V . P-P High accuracy for this MOSFET power amplifier is achieved with a cascode input circuit configuration. External compensation provides user flexibility by allowing customers to tailor slew rate and bandwidth per- formance. A resistor configurable current limit provides system level protection.
