DESCRIPTION
The PA41/42 are high voltage monolithic MOSFET opera-
tional amplifiers achieving performance features previously
found only in hybrid designs while increasing reliability. Inputs
are protected from excessive common mode and differential
mode voltages. The safe operating area (SOA) has no second
breakdown limitations and can be observed with all type loads
by choosing an appropriate current limiting resistor. External
compensation provides the user flexibility in choosing
optimum gain and bandwidth for the application.
The PA41 is packaged in a hermetically sealed TO-3 and all
circuitry is isolated from the case by an aluminum nitride (AlN)
substrate.
The PA42 is packaged in APEX’s hermetic ceramic SIP10
package.

TYPICAL APPLICATION
NOTE: PA41 Recommended mounting torque is 4-7 inlbs
(.45 -.79 Nm)
CAUTION: The use of compressible, thermally conductive
insulators may void warranty.
LOW COST 660V p-p
PIEZO DRIVE
Two PA41/42 amplifiers operated as a bridge driver for a
piezo transducer provides a low cost 660 volt total drive capa-
bility. The R
N CN network serves to raise the apparent gain of A2
at high frequencies. If R
N is set equal to R the amplifiers can be
compensated identically and will have matching bandwidths.
