DESCRIPTION
The PA51 and PA51A are high voltage, high output current
operational amplifiers designed to drive resistive, inductive
and capacitive loads. Their complementary common emitter
output stage is the simple class C type optimized for low
frequency applications where crossover distortion is not criti-
cal. These amplifiers are not recommended for audio, trans-
ducer or deflection coil drive circuits. The safe operating area
(SOA) is fully specified and can be observed for all operating
conditions by selection of user programmable current limiting
resistors. 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
reliability, minimize size and give top performance. Ultrasoni-
cally bonded aluminum wires provide reliable interconnec-
tions at all operating temperatures. The 8-pin TO-3 package is
electrically isolated and hermetically sealed. The use of com-
pressible thermal washers and/or improper mounting torque
will void the product warranty. Please see “General Operating
Considerations”.
EQUIVALENT SCHEMATIC
TYPICAL APPLICATION
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 Op Amp
insure accuracy. With this closed loop operation, temperature
induced impedance variations of the motor winding are auto-
matically compensated.
