PA08A - Power Operational Amplifier, 300V, 15A, "A" Grade
The PA08 is a high voltage operational amplifier designed for output voltage swings of up to ±145V with a dual (±) supply or 290V with a single supply. High accuracy is achieved
with a cascode input circuit configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA08 features an unprecedented supply range and excellent supply rejection. The output stage is biased-on for linear operation. Internal phase compensation assures stability at all gain settings. The safe operating area (SOA) can be observed with all types of loads by choosing the appropriate current limiting resistors.
For operation into inductive loads, two external flyback pulse protection diodes
are recommended. A heatsink may be necessary to maintain the proper case temperature under normal operating conditions. This hybrid integrated circuit utilizes beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semiconductor chips to maximize reliability, minimize size and give top performance.
Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 8-pin TO-3 package is hermetically sealed and electrically isolated. The
use of compressible thermal isolation washers and/or improper mounting torque will void the product warranty.
