AD9826KRSZ

The AD9826KRSZ is a Complete 16-bit Imaging Signal Processor features a 3-channel architecture designed to sample and condition the outputs of tri-linear colour 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 15MSPS 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. The 16-bit digital output is multiplexed into an 8-bit output word, which is accessed using two read cycles. There is an optional single byte output mode. The internal registers are programmed through a 3-wire serial interface and provide adjustment of the gain, offset and operating mode. It operates from a single 5V power supply, typically consumes 400mW of power.
