HT82V38 - Holtek Semiconductor

HT82V38 16-Bit CCD/CIS Analog Signal Processor

The HT82V38 is a complete analog signal processor for CCD 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/.
