General Description  
The HT82V26 is a complete analog signal processor for  
CCD imaging applications. It features a 3-channel archi-  
tecture designed to sample and condition the outputs of  
tri-linear color CCD arrays. Each channel consists of an  
input clamp, Correlated Double Sampler (CDS), offset  
DAC and Programmable Gain Amplifier (PGA), and a  
high performance 16-bit A/D converter.  
The 16-bit digital output is multiplexed into an 8-bit out-  
put word that is accessed using two read cycles. The in-  
ternal registers are programmed through a 3-wire serial  
interface, which provides gain, offset and operating  
mode adjustments.  
The HT82V26 operates from a single 5V power supply,  
typically consumes 400mW of power.  
The CDS amplifiers may be disabled for use with sen-  
sors such as Contact Image Sensors (CIS) and CMOS  
active pixel sensors, which do not require CDS.
