Description

The AD9826KRSZ-RL is a complete analog signal processor designed for imaging applications. It features a 3-channel architecture and is specifically designed for trilinear color CCD arrays. Each channel includes an input clamp, Correlated Double Sampler (CDS), offset DAC, and Programmable Gain Amplifier (PGA). This processor also includes a high-performance 16-bit A/D converter and can operate at speeds greater than 15 MSPS. The CDS amplifiers can 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.
