Holtek Semiconductor HT82V42
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.| Part No. | HT82V42 |

GENERAL 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 available in 4-bit wide multiplexed format. The internal registers are programmed through a 4-wire serial interface, which provides gain, offset and operating mode adjustments. The HT82V42 operates from a single 3.3V power supply and typically consumes 188mW of power. Block Diag...
