The AD9806 is a complete analog signal processor for CCD applications. It features an 18 MHz single-channel architecture, supporting 0 dB to 34 dB gain range of low noise PGA, low noise clamp circuits and analog pre-blanking function.
The AD9806 is a complete analog signal processor for CCD applications. It integrates an input clamp, correlated double sampler, programmable gain amplifier, black‑level clamp and a 10‑bit A/D converter, and provides two auxiliary 8‑bit DACs. The device operates from a single 3 V supply and is offered in a 48‑lead LQFP package.
Key features include a temperature range of –20 °C to +85 °C, low power consumption (75 mW at 3.0 V), a maximum clock rate of 18 MHz, and programmable gain from 0 dB to 34 dB (CCD mode) or –4 dB to +14 dB (AUX‑MID mode). The part supports a 3‑wire serial interface for register programming and includes ESD protection.
