DESCRIPTION

The PA84 is a high voltage operational amplifier 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 amplifier can absorb differential input over- voltages 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 configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA84 features an unprecedented supply range and excellent supply rejection. The output stage is biased- on for linear operation. External phase compensation allows for user flexibility in obtaining the maximum slew rate. Fixed current limits protect these amplifiers against shorts to common at supply voltages up to 150V. For operation into inductive loads, two external flyback pulse protection diodes are recommended. However, a heatsink may be necessary to maintain the proper case temperature under normal operating conditions. This hybrid integrated circuit utilizes a beryllia (BeO) sub- strate, thick film resistors, ceramic capacitors and semicon- ductor 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 war- ranty. Please see “General Operating Considerations”.

The external compensation network has been optimized to match the gain setting of the circuit and the complex impedance of the ink jet control unit. The combi- nation of speed and high voltage capabilities of the PA84 form ink droplets of uniform volume at high production rates to enhance the value of the printer.

Signal slew rates at pins 5 and 6 must be limited to less than 1V/ns to avoid damage. When faster waveforms are unavoidable, resistors in series with those pins, limiting current to 150mA will protect the amplifier from damage. 2. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. 3. The power supply voltage for all tests is ±150V, unless otherwise noted as a test condition. 4. Doubles for every 10°C of temperature increase. 5. +V S and –VS denote the positive and negative power supply rail respectively. 6. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz.
