DESCRIPTION
The PA96 is a state of the art high voltage, high current
operational amplifier designed to drive resistive, capacitive
and inductive loads. For optimum linearity, the output stage
is biased for class A/B operation. External compensation
provides user flexibility in maximizing bandwidth at any gain
setting. The safe operating area (SOA) can be observed for
all operating conditions by selection of user programmable
current limit. For continuous operation under load, a heatsink
of proper rating is required.
The 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.

PZT POSITION CONTROL
The MOSFET output stage of the PA96 provides superior
SOA performance compared to bipolar output stages where
secondary breakdown is a concern. The extended SOA is
ideal in applications where the load is highly reactive and
may impose simultaneously both high voltage and high cur-
rent across the output stage transistors. In the figure above
a piezo-electric transducer is driven to high currents and high
voltages by the PA96.
