FEATURES  
T he AD9826 is a complete analog signal processor for imaging  
applications. It features a 3-channel architecture designed to  
sample and condition the outputs of trilinear color CCD arrays.  
Each channel consists of an input clamp, Correlated Double  
Sampler (CDS), offset DAC, and Programmable Gain Amplifier  
(PGA), multiplexed to a high-performance 16-bit A/D converter.  
16-Bit 15 MSPS A/D Converter  
3-Channel 16-Bit Operation up to 15 MSPS  
1-Channel 16-Bit Operation up to 12.5 MSPS  
2-Channel Mode for Mono Sensors with Odd/Even Outputs  
Correlated Double Sampling  
1~6
؋
 Programmable Gain  
؎300 mV Programmable Offset  
Input Clamp Circuitry  
Internal Voltage Reference  
Multiplexed Byte-Wide Output  
Optional Single Byte Output Mode  
3-Wire Serial Digital Interface  
3 V/5 V Digital I/O Compatibility  
28-Lead SSOP Package  
T he AD9826 can operate at speeds greater than 15 MSPS with  
reduced performance.  
T he CDS amplifiers may be disabled for use with sensors that  
do not require CDS, such as Contact Image Sensors (CIS),  
CMOS active pixel sensors, and Focal Plane Arrays.  
The 16-bit digital output is multiplexed into an 8-bit output word,  
which is accessed using two read cycles. T here is an optional  
single byte output mode. T he internal registers are programmed  
through a 3-wire serial interface, and provide adjustment of  
the gain, offset, and operating mode.  
Low Power CMOS: 400 mW (Typ)  
Power-Down Mode Available  
APPLICATIONS  
Flatbed Document Scanners  
Digital Copier  
T he AD9826 operates from a single 5 V power supply, typically  
consumes 400 mW of power, and is packaged in a 28-lead SSOP.
