DESCRIPTION

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.

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” .

TYPICAL APPLICATION

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.
