DESCRIPTION
The PA07 is a high voltage, high output current operational
amplifier designed to drive resistive, inductive and capacitive
loads. For optimum linearity, especially at low levels, the
output stage is biased for class A/B operation using a thermistor compensated base-emitter voltage multiplier circuit. A
thermal shutoff circuit protects against overheating and minimizes heatsink requirements for abnormal operating conditions. The safe operating area (SOA) can be observed for all
operating conditions by selection of user programmable current limiting resistors. Both amplifiers are internally compensated for all gain settings. For continuous operation under
load, a heatsink of proper rating is recommended.
This hybrid circuit utilizes thick film (cermet) 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
washers and/or improper mounting torque will void the product
warranty. Please see “General Operating Considerations”.

TYPICAL APPLICATION
Negates optoelectronic instabilities
Lead network minimizes overshoot
SEQUENTIAL POSITION CONTROL
Position is sensed by the differentially connected photo
diodes, a method that negates the time and temperature
variations of the optical components. Off center positions
produce an error current which is integrated by the op amp
circuit, driving the system back to center position. A momentary switch contact forces the system out of lock and then the
integrating capacitor holds drive level while both diodes are in
a dark state. When the next index point arrives, the lead
network of C1 and R1 optimize system response by reducing
overshoot. The very low bias current of the PA07 augments
performance of the integrator circuit.

NOTES: * The specification of PA07A is identical to the specification for PA07 in applicable column to the left.
1. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation
to achieve high MTTF.
2. The power supply voltage for all specifications is the TYP rating unless otherwise noted as a test condition.
3. Doubles for every 10°C of temperature increase.
4. +VS and –VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to –VS.
5. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz.
CAUTION
The internal substrate contains beryllia (BeO). Do not break the seal. If accidentally broken, do not crush, machine, or
subject to temperatures in excess of 850°C to avoid generating toxic fumes.
