DESCRIPTION
The PA02 and PA02A are wide-band, high output current operational amplifiers designed to drive resis-
tive, inductive and capacitive loads. Their complementary “collector output” stage can swing close to the sup-
ply rails and is protected against inductive kickback. For optimum linearity, the output stage is biased for class
A/B operation. The safe operating area (SOA) can be observed for all operating conditions by selection of user
programmable, current limiting resistors (down to 10mA). Both amplifiers are internally compensated but are
not recommended for use as unity gain followers. For continuous operation under load, mounting on a heat-
sink of proper rating is recommended.
These hybrid integrated circuits utilize thick film (cermet) 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. Isolation washers are not recommended. The use of compressible thermal
washers and/or improper mounting torque will void the product warranty. Please see Application Note 1
“General Operating Considerations.”

SPECIFICATIONS
The power supply voltage for all specifications is the TYP rating unless otherwise noted as a test condi-
tion. Full temperature specifications are guaranteed but not 100% tested. The absolute maximum negative
input voltage is equal to the negative power supply voltage plus 1V (-Vs + 1V).

1. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dis-
sipation to achieve high MTTF.
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.
