Description
Analog ground
Reference level sampling pulse input
Data level sampling pulse input
ADC sampling clock input
Clamp control input
Low : Clamp operation “ON”
High : Clamp operation “OFF”
This should be fixed to Low during CDS mode
Analog power supply
Analog ground
Digital ground
Digital power supply
left open or should be connected to VSS
ADC output in a straight binary code( DC0 : LSB side , DC4 : MSB
side )
In 5 Bit-wide output operation in 3-channel and 6 channel modes,
Data output corresponds to CCDIN4 and CCDIN5.
In 10 Bit-wide output operation and in 5 Bit-wide output operation in 1
channel, 2 channel and 4 channel modes, these outputs are not used.
When these modes are selected, low level is output in normal operation
and either low level or high-Z output is programmable in power-down
mode by register setting.

ADC output in a straight binary code.
Signal name with parenthesis means a signal name in 10 Bit-wide
output operation ( in 5 Bit-wide output operation, DB0 : LSB side, DB4 :
MSB side and in 10 Bit-wide output operation, D0 : LSB ).
When in 5 Bit-wide output operation in 1 channel mode, these outputs
are not used. They become low level output in normal operation and
either low level or high-Z output is programmable by register setting in
power-down mode.
