Precautions for design-ins
(1)
Observe precautions for handling because of electro-static sensitive devices.
(2)
Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation).
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
(3)
The bypass capacitor should be attached to V
CC
line.
(4)
The inductor (L) should be attached between V
CC
pin and output pin.
The L and series capacitor (C2) values should be adjusted for applied frequency to match impedance to next
stage.
(5)
The DC cut capacitor must be attached to input pin.
(6)
You should apply voltage to V
CC
pin and output pin. You must not apply voltage to input pin nor regulate input
pin voltage (e.g. direct DC pull-down).
