PRODUCT DESCRIPTION

The AD9826 is a complete analog signal processor for 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/D converter.

The AD9826 can operate at speeds greater than 15 MSPS with reduced performance. The CDS amplifiers may be disabled for use with sensors that do not require CDS, such as Contact Image Sensors (CIS), CMOS active pixel sensors, and Focal Plane Arrays.
