description
The PA02 and PA02A are wideband, high output current
operational amplifiers designed to drive resistive, inductive
and capacitive loads. Their complementary “collector output”
stage can swing close to the supply 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 heatsink of
proper rating is recommended.
These hybrid integrated circuits utilize thick film (cermet)
resistors, ceramic capacitors and semiconductor chips to
maximize reliability, minimize size and give top performance.
Ultrasonically bonded aluminum wires provide reliable inter-
connections at all operating temperatures. The 8-pin TO-3
package is hermetically sealed and electrically isolated. Iso-
lation washers are not recommended. The use of compress-
ible thermal washers and/or improper mounting torque will
void the product warranty. Please see “General Operating
Considerations”
.
LOW INTERNAL LOSS MAXIMIZES EFFICIENCY
When system voltages are low and power is at a premium,
the PA02 is a natural choice. The circuit above utilizes not only
the feature of low internal loss of the PA02, but also its very
low distortion level to implement a crystal clear audio amplifier
suitable even for airborne applications. This circuit uses AC
coupling of both the input signal and the gain circuit to render
DC voltage across the speaker insignificant. The resistor and
capacitor across the inputs form a stability enhancement net-
work. The 0.27 ohm current limit resistors provide protection
in the event of an output short circuit.

NOTES: * The specification of PA02A is identical to the specification for PA02 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. +V
S
and –V
S
denote the positive and negative supply rail respectively. Total V
S
is measured from +V
S
to –V
S
.
4. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz.
5. Exceeding CMV range can cause the output to latch.
6. Full temperature specifications are guaranteed but not 100% tested.
7. The absolute maximum negative input voltage is equal to the negative power supply voltage plus 1V (-Vs + 1V).
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.

Proper operation requires the use of two current limit resistors, connected as shown
in the external connection diagram. The minimum value for R

is 0.12 ohm, however for
optimum reliability it should be set as high as possible. Refer to the “General Operating

deVice mounting
The case (mounting flange) is electrically isolated and should be mounted directly
to a heatsink with thermal compound. Screws with Belville spring washers are recom-
mended to maintain positive clamping pressure on heatsink mounting surfaces. Long
periods of thermal cycling can loosen mounting screws and increase thermal resistance.
Since the case is electrically isolated (floating) with respect to the internal circuits
it is recommended to connect it to common or other convenient AC ground potential.
