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 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.
