Holtek Semiconductor HT82V24
The HT82V24 is a complete analog signal processor for CCD imaging applications. It features a 3-channel architecture 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.| Part No. | HT82V24 |

APPLICATIONS
Flatbed document scanners Film scanners Digital color copiers Multifunction peripheralsGENERAL DESCRIPTION
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. The 16-bit digital output is multiplexed into an 8/4-bit output word that is accessed using two/four read cycles.
