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 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 “General Operat­ing Considerations”.

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
network. 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. +VS and –VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to –VS.

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.

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.
