DESCRIPTION

The PA51 and PA51A are high voltage, high output current

operationalampliﬁersdesignedtodriveresistive,inductiveand

capacitiveloads.Theircomplementarycommonemitteroutput

stage is the simple class C type optimized for low frequency

applications where crossover distortion is not critical. These

ampliﬁersarenotrecommendedforaudio,transducerordeﬂec-

tion coil drive circuits. The safe operating area (SOA) is fully

speciﬁed and can be observed for all operating conditions by

selectionofuserprogrammablecurrentlimitingresistors.Both

ampliﬁers are internally compensated for all gain settings.For

continuous operation under load, mounting on a heatsink of

proper rating is recommended. Do not use isolation washers!

This hybrid integrated circuit utilizes thick ﬁlm conductors,

ceramic capacitors and semiconductor chips to maximize reli-

ability, minimize size and give top performance.Ultrasonically

bonded aluminum wires provide reliable interconnections at

all operating temperatures.The 8-pinTO-3 package is electri-

cally isolated and hermetically sealed.The use of compress-

ible thermal washers and/or improper mounting torque will

void the product warranty. Please see “General Operating

Considerations”.

MOTOR CURRENT IS A FUNCTION OF V_IN

PROGRAMMABLE TORQUE CIRCUIT

The linear relationship of torque output to current input of

the modern torque motor makes this simple control circuit

ideal for many material processing and testing applications.

The sense resistor develops a feedback voltage proportional

to motor current and the small signal properties of the Power

OpAmp insure accuracy.With this closed loop operation, tem-

perature induced impedance variations of the motor winding

are automatically compensated.
