DESCRIPTION
The PA41/42 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 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.

LOW COST 660V p-p PIEZO DRIVE
175
Two PA41/42 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 specification for PA41A/PA42A is identical to the specification for PA41/PA42 in applicable column to the left. Unless otherwise noted TC = 25°C, CC = 18pF, RC = 2.2K. DC input specifications are ± value given. Power supply voltage is typical rating. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. For guidance, refer to heatsink data sheet. Derate maximum supply voltage .5 V/°C below case temperature of 25°C. No derating is needed above TC = 25°C. Sample tested by wafer to 95%. Guaranteed but not tested. The selected value of RCL must be added to the values given for total output resistance. Specifications separated by / indicate values for the PA41 and PA42 respectively. The PA41/PA42 is constructed from MOSFET transistors. ESD handling procedures must be observed.
