PA243DF
PA243DF Datasheet
The PA243 is a dual high voltage monolithic MOSFET operational amplifier achieving performance features previously found only in hybrid designs while increasing reliability. This approach provides a cost-effective solution to applications where multiple amplifiers are required. Inputs are protected from excessive common mode and differential mode voltages. The safe operating area SOA has no secondary 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 safe operating area SOA has no secondary 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 PA243DF is packaged in a 24 pin PSOP JEDEC MO-166 package. The heatslug of the PA243DF package is isolated in excess of full supply voltage. +175 20R +175 10pF 10pF PA243 R CL R CL PA243 PIEZO 47 TRANSDUCER 47 Low Cost 660v p-p Piezo Drive A single PA243 amplifier operates as a bridge driver for a piezo transducer providing 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.
