PA164/PA165 RoHS High Voltage Power Operational Amplifiers COMPLIANT FEATURES Monolithic MOS Technology for Amplifier Core High Voltage Operation (200V Output) Current Limit with Over-current Flag High Output Current 4A Peak or 10A Peak Amplifier Disable feature APPLICATIONS High Density Voltage or Current Supplies Electrostatic Transducer and Deflection Deformable Mirror Focusing Piezo Electric Positioning DESCRIPTION The PA164 and PA165 are high voltage MOSFET operational amplifiers with a monolithic amplifier core designed for high density power applications with high output currents or voltages. Both devices are designed for operation up to 200V, with the PA164 providing 1A and the PA165 4A of continuous current. Separate supplies for the amplifier core and the output stage optimize the overall power dissipation in the devices. Both devices offer a wide-range, temperature compensated current limit. An additional over-current flag allows for a flexible implementation of system protection, with an output disable function adding another layer of optional protection. External compensation provides the user flexibility in choosing optimum gain and bandwidth for the application. Apex Microtechnology Inc.
