peak pulsed currents.
Similarly, the maximum continuous source current can be
calculated as
where V
is the voltage drop across hybrid output stage
DIODE
which varies over temperature and can be assumed to be
about 1.1V at T
(max) of 125˚C. Assuming the same param-
J
eters as above, this equation yields I
(max) of 347mA.
