Holtek Semiconductor HT82V46
The HT82V46 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. | HT82V46 |

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 8-bit wide multiplexed format. The internal registers are programmed through a 4-wire serial interface, which provides gain, offset and operating mode adjustments. The HT82V46 operates from a single 3.3V power supply, typically consumes 528mW of power.APPLICATIONS
