DESCRIPTION
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 com-
pensation 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) sub-
strate, thick film resistors, ceramic capacitors and semicon-
ductor chips to maximize reliability, minimize size and give
top performance. Ultrasonically bonded aluminum wires pro-
vide reliable interconnections at all operating temperatures.
The 8-pin TO-3 package is hermetically sealed and electri-
cally isolated. The use of compressible thermal isolation
washers and/or improper mounting torque will void the prod-
uct warranty. Please see “General Operating Considerations”.

ATE PIN DRIVER
The PA08 as a pin driver is capable of supplying high test
voltages to a device under test (DUT). Due to the possibility of
short circuits to any terminal of the DUT, current limit must be
set to be safe when limiting with a supply to output voltage
differential equal to the amplifier supply plus the largest
magnitude voltage applied to any other pin of the DUT. In
addition, flyback diodes are recommended when the output of
the amplifier exits any equipment enclosure to prevent dam-
age due to electrostatic discharges. Refer to Application Note
7 for details on accuracy considerations of this circuit.

The specification of PA08A is identical to the specification for PA08 in applicable column to the left.
Long term operation at the maximum junction temperature will result in reduced product life. Derate power dissipation to
achieve high MTTF.
The power supply voltage specified under typical (TYP) applies unless otherwise noted.
Doubles for every 10oC of temperature increase.
+VS and –VS denote the positive and negative supply rail respectively.
Rating applies only if 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.
