High Voltage Power Operational Amplifiers. The safe operating area SOA has no second breakdown limitations and can be observed with all.
High accuracy is achieved with a cascode. As a result, the PA85 features an unprecedented supply range and excellent supply rejection. External compensation provides user flexibility. This hybrid circuit utilizes thick film cermet resistors, ceramic capacitors and silicon semiconductor. Ultrasonically bonded aluminum wires. The use of compressible isolation washers voids the warranty. Figure 1: Typical Connection. All rights reserved. July PA93U Rev S.
Figure 2: External Connections. Pin Number. The output. Connect this pin to load and to the feedback resistors. Connect to the current limit resistor, and then the OUT pin. Output current flows. The positive supply rail. The inverting input. The negative supply rail. Compensation resistor connection. Select value based on Phase Compensation. See applicable section. Compensation capacitor connection. Download PA85 Datasheet. The safe operating area SOA has no second breakdown limitations and can be observed with all types of loads by choosing an appropriate current limiting resistor.
High accuracy is achieved with a cascode input circuit configuration. This hybrid circuit utilizes thick film cermet resistors, ceramic capacitors and silicon semiconductor chips to maximize reliability, minimize size and give top performance.
Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures.
