General Description  
The HT82V38 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  
trilinear color CCD arrays. Each channel consists of an  
input clamp, Correlated Double Sampler (CDS), offset  
DAC and Programmable Gain Amplifier (PGA), multi-  
plexed to 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, and provide adjustment of the gain, offset, and  
operating mode.  
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.
