On-Chip CDS—An integrated 3-channel correlated double  
The AD9807 and AD9805 are complete CCD/CIS imaging  
decoders and signal processors on a single monolithic integrated  
circuit. T he input of the AD9807/AD9805 allows direct ac  
coupling of the charge-coupled device (CCD) or contact image  
sensor (CIS) output(s). T he AD9807/AD9805 includes all the  
circuitry to perform three-channel correlated double sampling  
(CDS) and programmable gain adjustment of the CCD output;  
a 12-bit or 10-bit analog-to-digital converter (ADC) quantizes  
the analog signal. After digitization, the on-board digital signal  
processor (DSP) circuitry allows pixel rate offset and gain correc-  
tion. The DSP also corrects odd/even CCD register imbalance  
errors. A parallel control bus provides a simple interface to  
8-bit microcontrollers. T he AD9807/AD9805 comes in a  
space saving 64-pin plastic quad flatpack (PQFP) and is specified  
over the commercial (0°C to +70°C) temperature range. By  
disabling the CDS, the AD9807/AD9805 are also suitable for  
non-CCD applications, or applications that do not require  
CDS, such as CIS signal processing.  
sampler allows easy ac coupling directly from the CCD sensor  
outputs. Additionally, the CDS reduces low frequency noise  
and reset feedthrough.  
On-Chip Voltage Reference—T he AD9807/AD9805 includes a  
2 V bandgap reference that allows the input range of the device to  
be configured for input spans up to 4 V.  
6 MSPS A/D Converter—A highly linear 12-bit or 10-bit A/D  
converter sequentially digitizes the red, green and blue CDS  
outputs ensuring no missing code performance. The user may also  
configure the AD9807/AD9805 for single channel operation.  
Digital Gain & Offset Correction—Pixel rate digital gain and  
offset correction blocks allow precise repeatable correction of  
imaging system error sources.  
Digital I/O CompatibilityThe AD9807/AD9805 offers  
+3.3 V/+5 V logic level compatibility.  
Pin-Compatible 12-Bit and 10-Bit Versions—T he AD9807 is  
also offered in a pin-compatible 10-bit version, the AD9805,  
allowing upgrade-ability and simplifying design issues across  
different scanner models.  
P RO D UCT H IGH LIGH TS  
T he AD9807/AD9805 offers a complete, single chip CCD  
imaging front end in a 64-pin plastic quad flatpack (PQFP).  
On-Chip PGA—T he AD9807/AD9805 includes a 3-channel  
analog programmable gain amplifier; it is programmable from  
1× to 4× in 16 increments.
