General Description
The HT82V42 is a complete analog signal processor for CCD imaging applications. It features a 1-channel architecture designed to sample and condition the outputs of tri-linear color CCD arrays. The 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 CDS amplifiers may be disabled for use with sensors such as Contact Image Sensors (CIS) and CMOS active pixel sensors, which do not require CDS.
