The output voltage of DC/DC converter is toggled ON/OFF by changing voltage to
this terminal to High/Low.
The positive voltage of this terminal is supplied to op-amp 1 in the DC/DC
converter, and its output voltage (negative) is internally supplied to the gate ports
of #1 to 3 amplifiers. The current of amplifier is controlled by the voltage of this
terminal.
The voltage of the gate ports of #1 to 3 amplifier are supplied through this
terminal. Please place a capacitor at this terminal as close as possible.
Ground terminal(0V)
This terminal is a signal input terminal connected to input port of amplifier through
matching circuit and DC blocking capacitor.
Ground terminal(0V)
Ground terminal(0V)
This terminal is Connected to gate fourth stage amplifier. Please connect with -

Ground terminal(0V)
This terminal is a signal output terminal connected to the output port of amplifier
through matching circuit and DC blocking capacitor.
Ground terminal(0V)
This terminal is connected to drain port of fourth stage amplifier. Please place a
choke inducter and a bypass capacitor shown in the application circuit below.
Ground terminal(0V)
The voltage of the gate ports of #1 to 3 amplifier are supplied through this
terminal. Please place a capacitor at this terminal as close as possible.
Ground terminal(0V)
Ground terminal(0V)
This terminal is a gain control terminal of amplifier, and also internally connected
to output port of op-amp2. Please place a bypass capacitor at this terminal shown
in the application circuit below as close as possible.
The positive voltage of this terminal is supplied to op-amp2 in the DC/Dc
converter, and its output voltage(negative) is internally supplied to the gain
control port of amplifier. The gain of amplifier is controlled by the voltage of this
terminal.
This terminal is a voltage supply terminal of DC/DC converter. Please place
bypass capacitor shown in the application circuit below as close as possible.
