TYPICAL APPLICATION
FIGURE 1. VOLTAGE-TO-CURRENT CONVERSION
DC and low distortion AC current waveforms are delivered
to a grounded load by using matched resistors (A and B
sections) and taking advantage of the high common mode
rejection of the PA10.
Foldover current limit is used to modify current limits based
on output voltage. When load resistance drops to 0, the cur-
rent is limited based on output voltage. When load resistance
drops to 0, the current limit is 0.79A resulting in an internal
dissipation of 33.3 W. When output voltage increases to
36V, the current limit is 1.69A. Refer to Application Note 9 on
foldover limiting for details.

DESCRIPTION
The PA10 and PA10A are high voltage, high output current
operational amplifiers designed to drive resistive, inductive
and capacitive loads. For optimum linearity, the output stage
is biased for class A/B operation. The safe operating area
(SOA) can be observed for all operating conditions by selec-
tion of user programmable current limiting resistors. Both
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) resis-
tors, ceramic capacitors and semiconductor chips to maximize
reliability, minimize size and give top performance. Ultrasonically
bonded aluminum wires provide reliable interconnections at all
operating temperatures. The 8-pin TO-3 package is hermeti-
cally sealed and electrically isolated. The use of compressible
isolation washers voids the warranty.
