The single ended input MI3 behaves like one of the differential input pins, in case of one
input of the differential inputs is tied to
figure 9 introduces no new ideas. An electret microphone can be biased from
(figure 9a) or from the
reference to ground should be connected between the MI3 pin and the
(figure 9c). Often MI3 is used as a additional input e.g. for separate microphones with
their own preamplifiers. Such high-level signal sources could be connected to MI3 as
shown in figure 9d.
In general, if only two inputs are required, it is advisable to use MIN1/MIP1 and
MIN2/MIP2 for this purpose. They exhibit a slightly better performance because of their
differential nature. Unused inputs can be left open or tied to
