MP165 RoHS High Voltage Power Operational Amplifier COMPLIANT FEATURES Monolithic MOS Technology for Amplifier Core High Voltage Operation (200V Output) Current Limit with Over-Current Flag High Output Current 4A continuous and 10A Peak Amplifier Disable Feature APPLICATIONS High Density Voltage or Current Supplies Electrostatic Transducer and Deflection Deformable Mirror Focusing Piezo Electric Positioning DESCRIPTION The MP165 is a high voltage, MOSFET based operational amplifier with a monolithic amplifier core devel- oped for high density power applications with high output currents or voltages. It is designed for operation up to 200V, and 4A of continuous current. Separate supplies for the amplifier core and the output stage opti- mize the overall power dissipation in the devices. The MP165 offers a wide-range (4000:10), 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. Pins for external compensation provides the user flexibility in choosing optimum gain and bandwidth for the application. The V pin helps in measuring the case temperature of the amplifier.
