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 VIN  
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.
