Input terminal.
Non-bias. It is possible to use with being directly connected
with DC. When DC coupling, it is necessary to add bias
after the coupling. Using with +power supply, it is better to
set at 1/2 VCC.

Output terminal.
Using
±power supply, it is possible to use without capacitor
of output by setting the input to zero-bias. When using
+power supply, coupling capacitor is necessary.
