DESCRIPTION  
A1  
A2  
The PA141/PA142 are high voltage monolithic MOSFET  
operational 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 com-  
pensation provides the user flexibility in choosing  
optimum gain and bandwidth for the application.

PIEZO DRIVE  
–175  
–175  
Two PA141/PA142 amplifiers operated as a bridge driver  
for a piezo transducer provides a low cost 660 volt total drive  
capability. The RN CN network serves to raise the apparent  
gain of A2 at high frequencies. If RN is set equal to R the  
amplifiers can be compensated identically and will have  
matching bandwidths.  
The PA141 is packaged in a hermetically sealed TO-3  
and all circuitry is isolated from the case by an aluminum  
nitride (AlN) substrate.  
The PA142 is packaged in APEX’s hermetic ceramic  
SIP package.
