DESCRIPTION

The PA01 and PA73 are high voltage, high output current

operational ampliﬁers designed to drive resistive, inductive

and capacitive loads. For optimum linearity, the PA01 has a

class A/B output stage. The PA73 has a simple class C output

stage (see Note 1) to reduce cost for motor control and other

applications where crossover distortion is not critical and to

provide interchangeability with type 3573 ampliﬁers. The

safe operating area (SOA) can be observed for all operating

conditions by selection of user programmable current limit

resistors. These ampliﬁers are internally compensated for all

gain settings. For continuous operation under load, a heatsink

of proper rating is recommended.

This hybrid integrated circuit utilizes 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. The

use of compressible thermal washers and/or improper mount-

ing torque will void the product warranty. Please see “General

Operating Considerations”.

Unidirectional Optical Speed Control

The pulse output of a non-contact optical sensor drives a

voltage-to-frequency converter which generates feedback for

the op amp. With the loop closed in this manner, the op amp

corrects for any variations in the speed due to changing load.

Because of operation in only one direction, an unsymmetrical

supply is used to maximize efﬁciency of both power op amp

and power supply. High speed diodes at the input protect the

op amp from commutator noise which may be generated by

the motor.

OPERATING

CONSIDERATIONS

PA01 • PA73

1. For sine wave outputs, use Power Design

to plot a load

line. Make sure the load line does not cross the 0.5ms limit

and that excursions beyond any other second breakdown

line do not exceed the time label, and have a duty cycle of

no more than 10%.

For other waveform outputs, manual load line plotting

is recommended. Applications Note 22, SOA AND LOAD

LINES, will be helpful. A Spice type analysis can be very

useful in that a hardware setup often calls for instruments

or ampliﬁers with wide common mode rejection ranges.

2. EMF generating or reactive load and short circuits to the

supply rail or shorts to common are safe if the current limits

are set as follows at T

= 85°C.

GENERAL

Please read Application Note 1 "General Operating Con-

siderations" 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, in-

ternal power dissipation, current limit and heat sink selection.

The "Application Notes" and "Technical Seminar" sections

contain a wealth of information on speciﬁc types of applications.

Package outlines, heat sinks, mounting hardware and other

accessories are located in the "Packages and Accessories"

section. Evaluation Kits are available for most Apex product

models, consult the "Evaluation Kit" section for details. For

the most current version of all Apex product data sheets, visit

www.apexmicrotech.com.

SAFE OPERATING AREA (SOA)

The output stage of most power ampliﬁers has three distinct

limitations:

1. The current handling capability of the transistor geometry

and the wire bonds.

2. The second breakdown effect which occurs whenever the

simultaneous collector current and collector-emitter voltage

exceeds speciﬁed limits.

3. The junction temperature of the output transistors.

3. The output stage is protected against occaisional transient

ﬂyback. However, for protection against sustained, high

energy ﬂyback, external fast-recovery diodes should be

used.

CURRENT LIMIT

Proper operation requires the use of two current limit resis-

tors, 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 Considerations” section of the handbook

for current limit adjust details.

½½

½½½½½½½½½½

½½

½½ ½½ ½½

½½

The SOA curves combine the effect of these limits. For a

given application, the direction and magnitude of the output

current should be calculated or measured and checked against

the SOA curves. This is simple for resistive loads but more

complex for reactive and EMF generating loads.
