High Slew Rate 200V/µs, High Voltage 350V Power Amplifier

The PA84 is a high voltage operational ampliier designed for output voltage swings up to 145V with a dual supply or 290V with a single supply. Two versions are available. The new PA84S fast settling ampliier CAN absorb differential input overvoltages up to 50V while the established PA84 and PA84A CAN handle differential input overvoltages of up to 300V. Both versions are protected against common mode transients and overvoltages up to the supply rails. High accuracy is achieved with a cascode input circuit coniguration. All internal biasing is referenced to a Zener Diode fed by a FET constant current source. As a result, the PA84 features an unprecedented sup- ply range and excellent supply rejection. The output stage is biased-on for linear operation. External phase compensation allows for user lexibility in obtaining the maximum slew rate. Fixed current limits protect these ampliiers against shorts to common at supply voltages up to 150V. For operation into inductive loads, two external lyback pulse Protection Diodes are recommended. However, a heatsink may be necessary to maintain the proper case temperature under normal operating conditions. By Cirrus Logic, Inc.
