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.
