2. The offset voltage E
OB
is a potential difference between V
RB
and a point of position where the voltage drops equivalent to
1
/
2
LSB of the voltage
when the output data changes from “00000000” to “00000001”. E
OT
is a potential difference between V
RT
and a potential point where the
voltage rises equivalent to
1
/
2
LSB of the voltage when the output data changes from “11111111” to “11111110”.
3. The voltage of up to (AV
DD
+ 0.5V) can be input when DV
DD
= 3.3V. But the output pin voltage is less than the DV
DD
voltage. When the digital
output is in the high impedance mode, the IC may be damaged by applying the voltage which is more than the (DV
DD
+ 0.5V) voltage to the
digital output.
4. The clamp pulse width is for NTSC as an example. Adjust the rate to the clamp pulse cycle (1/15.75kHz for NTSC) for other processing systems
