FEATURES

• HIGH SLEW RATE — 200V/µs

• FAST SETTLING TIME — .1% in 1µs (PA84S)

• FULLY PROTECTED INPUT — Up to ±150v

• LOW BIAS CURRENT, LOW NOISE — FET Input

• WIDE SUPPLY RANGE — ±15V to ±150V

APPLICATIONS

• HIGH VOLTAGE INSTRUMENTATION

• ELECTROSTATIC TRANSDUCERS & DEFLECTION

• PROGRAMMABLE POWER SUPPLIES UP TO 290V

• ANALOG SIMULATORS

DESCRIPTION

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

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 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 sup-

ply 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.

strate, thick film resistors, ceramic capacitors and semiconduc-

tor 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.

control to deposit crisp clear date or lot code information on

product containers. The external compensation network has

been optimized to match the gain setting of the circuit and the

... TEMPERATURE RANGE, case NOTES: * The specification of PA84A is identical to the specification for PA84/PA84S in applicable column to the left. 1. 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. ...
