DESCRIPTION

amplifier which 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.

TO-3 package. The metal case of the PA241CE is isolated in

excess of full supply voltage.

166) package. The metal heat slug of the PA241DF is isolated

in excess of full supply voltage.

metic ceramic SIP package. The alumina ceramic isolates the

die in excess of full supply voltage.
