The document describes the complete 16-bit imaging signal processor AD9826 by Analog Devices. The processor features a 16-bit 15 MSPS A/D converter, capable of 3-channel 16-bit operation up to 15 MSPS. It also includes programmable gain and offset, as well as an internal voltage reference.
The AD9826 is a complete 16‑bit imaging signal processor designed for color CCD arrays. It features a three‑channel architecture, each channel with an input clamp, correlated double sampler, programmable offset DAC and programmable gain amplifier, all multiplexed to a high‑performance 16‑bit A/D converter.
The device operates from a single 5 V supply, consumes about 400 mW in 3‑channel mode, and supports up to 30 MSPS conversion in CDS mode. It is offered in a 28‑lead SSOP package and is used in flatbed scanners, digital copiers, machine‑vision and infrared imaging applications.
