Analog Devices AD9822 14‑Bit CCD/CIS Signal Processor Handbook
The AD9822 is a complete analog signal processor designed for CCD imaging applications. It features a three‑channel architecture that samples and conditions the output of trilinear color CCD arrays, with each channel providing input clamp, correlated double sampling (CDS), offset DAC, and programmable gain amplifier (PGA) before a high‑performance 14‑bit ADC. The device can operate in 3‑channel or 1‑channel modes and supports both CCD and CIS sensors.
The part is supplied in a 28‑lead SOIC or SSOP package, runs from a single 5 V analog supply, and consumes typically 385 mW. Detailed specifications cover analog and digital performance, timing, absolute maximum ratings, thermal characteristics, pin functions, and recommended circuit layouts for optimal operation.
