The PA341 is a next generation product in the Cirrus Logic family of low cost, high voltage power amplifiers that feature the technology of Apex Precision Power®. This pin compatible replacement for the PA241, is a monolithic MOSFET operational amplifier that 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 PA341CE is packaged in a hermetically-sealed 8-pin TO-3 package. The metal case of the PA341CE is isolated in excess of full supply voltage.
The PA341DF is packaged in a 24-pin PSOP (JEDEC MO-166) package with a metal heat slug that is isolated in excess of full supply voltage.
The PA341DW is packaged in 10-pin hermetic ceramic SIP package or “PowerSIP.” The alumina ceramic base used in this package isolates the die in excess of full supply voltage.
In transitioning to the PA341, the recommended values of some external components may change for optimal performance in certain applications; however, there should be no need for added components and the circuit board layout/artwork changes should not require revision.
