Function and Applications
Signal input pin. A internal
matching circuit, configured with
resistors, enables 50 Ω connec-
tion over a wide band.
A multi-feedback circuit is de-
signed to cancel the deviations of
hFE and resistance.
This pin must be coupled to sig-
nal source with capacitor for DC
cut.
Signal output pin. The inductor
must be attached between VCC
and output pins to supply current
to the internal output transistors.
IN 1
Power supply pin, which biases
the internal input transistor.
This pin should be externally
equipped with bypass capacitor
to minimize its impedance.
Ground pin. This pin should be
connected to system ground with
minimum inductance. Ground
pattern on the board should be
formed as wide as possible.
All the ground pins must be con-
nected together with wide ground
pattern to decrease impedance
defference.
