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 current
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 selection 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 recom-
mended.
This hybrid integrated circuit utilizes thick film (cermet)
resistors, ceramic capacitors and semiconductor chips to maxi-
mize reliability, minimize size and give top performance. Ultra-
sonically bonded aluminum wires provide reliable interconnec-
tions at all operating temperatures. The 8-pin TO-3 package is
hermetically sealed and electrically isolated. The use of com-
pressible isolation washers voids the warranty.
