DESCRIPTION
The PA241 is a high voltage monolithic MOSFET operational
amplifier which achieves 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 limitation 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 PA241CE is packaged in a hermetically sealed 8-pin
TO-3 package. The metal case of the PA241CE is isolated in
excess of full supply voltage.
The PA241DF is packaged in a 24 pin PSOP (JEDEC MO-
166) package. The metal heat slug of the PA241DF is isolated
in excess of full supply voltage.
The PA241DW is packaged in Apex’s hermetic ceramic SIP
package. The alumina ceramic isolates the die in excess of
full supply voltage.
EQUIVALENT SCHEMATIC
LOW COST 660V p-p
PIEZO DRIVE
Two PA241 amplifiers operated as a bridge driver for a piezo
transducer provides a low cost 660 volt total drive capability.
The R
C
network serves to raise the apparent gain of A2 at
high frequencies. If R
is set equal to R the amplifiers can be
compensated identically and will have matching bandwidths.
