DESCRIPTION
The PA52 is a MOSFET power operational amplifier that
extends the performance limits of power amplifiers in slew
rate and power bandwidth, while maintaining high current and
power dissipation ratings.
Boost voltage inputs allow the small signal portion of the
amplifier to operate at a higher voltage than the high current
output stage. The amplifier is then biased to achieve close
linear swings to the supply rails at high currents for extra efficient operation.
The JEDEC MO-127 12-pin Power Dip™ package (see
Package Outlines) is hermetically sealed and isolated from
the internal circuits. The use of compressible thermal washers
and/or improper mounting torque will void the product warranty.
Please see “General Operating Considerations”.

NOTES: * The specification of PA52A is identical to the specification for PA52 in applicable column to the left
1. Unless otherwise noted: TC = 25°C, DC input specifications are ± value given. Power supply voltage is typical rating.
±VBOOST = ±VS.
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to
achieve high MTTF. For guidance, refer to the heatsink data sheet.
3. Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz.
CAUTION
The PA52 is constructed from MOSFET transistors. ESD handling procedures must be observed.
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.

OPERATING
CONSIDERATIONS
PA52 • PA52A
GENERAL
COMPENSATION
Please read Application Note 1 "General Operating Considerations" which covers stability, supplies, heat sinking,
mounting, current limit, SOA interpretation, and specification
interpretation. Visit www.apexmicrotech.com for design tools
that help automate tasks such as calculations for stability,
internal power dissipation, current limit; heat sink selection;
Apex’s complete Application Notes library; Technical Seminar
Workbook; and Evaluation Kits.
Compensation is internally fixed for a gain of 3 or more and
is not adjustable by the user. The PA52 therefore is not unity
gain stable.
CURRENT LIMIT
There is no internal circuit provision for current limit in the
PA52. However, the PA52 circuit board in the PA52 evaluation
kit does provide a means whereby the output current can be
sensed. An external circuit current limit can thereby be implemented if needed. See EK27 data sheet for more details.
POWER SUPPLY BYPASSING
Proper and sufficient power supply bypassing is crucial to
proper operation of the PA52. Bypass the +Vb and -Vb supply
pins with a minimum .1µF ceramic capacitors directly at the
supply pins. On the +Vs and -Vs pins use a combination of
ceramic and electrolytic capacitors. Use 1µF ceramic capacitors and an electrolytic capacitor at least 10µF for each amp
of output current required.
BOOST OPERATION
With the VBOOST feature the small signal stages of the
amplifier are operated at higher supply voltages than the
amplifier’s high current output stage. +VBOOST (pin 11) and
–VBOOST (pin 12) are connected to the small signal circuitry of
the amplifier. +VS (pin 9,10) and –VS (pin 3,4) are connected to
the high current output stage. An additional 10V on the VBOOST
pins is sufficient to allow the small signal stages to drive the
output transistors into saturation and improve the output voltage
swing for extra efficient operation when required. When close
swings to the supply rails is not required the +VBOOST and +VS
pins must be strapped together as well as the –VBOOST and –VS
pins. The boost voltage pins must not be at a voltage lower
than the VS pins.
This data

is assumed for
possible inaccuracies
