GENERAL DESCRIPTION

The AD80066 is a complete analog signal processor for imaging applications. It features a 4-channel architecture designed to sample and condition the outputs of linear charged coupled device (CCD) or contact image sensor (CIS) arrays. Each channel consists of an input clamp, correlated double sampler (CDS), offset digital-to-analog converter (DAC), and programmable gain amplifier (PGA), multiplexed to a high performance 16-bit ADC. For maximum flexibility, the AD80066 can be configured as a 4-channel, 3-channel, 2-channel, or 1-channel device.
