PRECAUTIONS
Each V
CC1
to V
CC6
pin corresponds to the each
GND
1
to GND
6
pin. Connect a ceramic capacitor
as near the IC as possible between each
corresponding V
CC
pin and GND pin.
The GND
1
pin is the ground of the CDS/ADC
circuit handling a weak signal. Pay careful attention
to the board layout of the GND
1
pattern in order to
avoid the potential fluctuation of the GND
1
caused
by the current of the other GND pins. Especially
pay attention to the current of the GND
6
pin's
flowing spiky current.
All the GND pins must be at the same potential
and not open. And keep the potential difference of
each V
CC
pin within 0.3 V.
The high level voltage of the outputs of the A/D
converter is controllable by the voltage of the
V
LOGIC
pin, but take care that the high level voltage
does not fall below about 1.5 V, in spite of making
the V
LOGIC
pin 0 V. This may cause the latch up of
the following logic ICs if the power supply of this IC
rises up faster than the power supply of the
following logic. To avoid this problem, it is
recommended to make the ‰ pin low until the
voltage of the logic power supply becomes stable.
Take care too that the high level voltage does not
rise above about V
CC
– 1.0 V, in spite of making
the V
LOGIC
pin the V
CC
potential.
Restore the value of the serial register when setting
up the power supply or making the ‰ pin high
because the value will have been removed in that
case.
