General Description
The HT82V26A is a complete analog signal processor for CCD imaging applications. It features a 3-channel
architecture designed to sample and condition the out puts of tri-linear color CCD arrays. Each channel con
sists of an input clamp, Correlated Double Sampler (CDS), offset DAC and Programmable Gain Amplifier
(PGA), and a high performance 16-bit A/D converter.
