R1A

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.

R2B

This hybrid integrated circuit utilizes thick ﬁlm (cermet)

resistors, ceramic capacitors and semiconductor chips to

maximize reliability, minimize size and give top performance.

Ultrasonically bonded aluminum wires provide reliable inter-

connections at all operating temperatures. The 8-pin TO-3

package is hermetically sealed and electrically isolated. The

use of compressible isolation washers voids the warranty.

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 dissipa-

tion 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.
