Precautions for Design-ins
(1) Observe precautions for handling because of electro-static sensitive devices.
(2) Form a ground pattern as wide as possible to minimize ground impedance (to prevent undesired oscillation).
All the ground pins must be connected together in a wide ground pattern to decrease impedance difference.
(3) Keep the track length of the ground pins as short as possible.
(4) The bypass capacitor should be attached to the V
CC
pin.
(5) The DC cut capacitor must be each attached to the input and output pins.
(6) Refer to the data sheet of each product for the relevant cautions and electrical characteristics.
