BLKG
36
I
Control input. The CDS operation is disabled when BLKG is pulled low.
CLCCD
47
I
CCD signal clamp control input
CCDIN
1
I
CCD input
CLREF
48
O
Clamp-reference-voltage output
CP
34, 35
I
Connect these pins to AVDD
CS
28
I
Chip select. A logic low on this input enables the serial port.
D0 – D9
7–16
O
10-bit 3-state ADC output data or offset DACs test data
DACO1
21
O
Digital-to-analog converter output1
DACO2
22
O
Digital-to-analog converter output2
DGND

DIVDD
17
Digital-interface-circuit supply voltage, 1.8 V 4.4 V
DVDD
6
Digital-supply voltage, 3 V
NC
2
I
No connect
OBCLP
31
I
Optical black-level and offset-calibration control input, active low
OE
24
I
Output-data enable, active low
RBD
38
O
Internal bandgap reference for external decoupling
RESET
29
I
Hardware-reset input, active low. This signal forces a reset of all internal registers.
RMD
39

STBY
30
I
Hardware power-down control input, active low
SV
46
I
CCD signal-level sample clock input
VSS
42
Silicon substrate, normally connected to analog ground
