The AD9972 is a highly integrated, dual-channel CCD signal processor for high speed digital video camera applications. It features a 1.8V analog and digital core supply voltage, correlated double sampler (CDS), variable gain amplifier (VGA) with 6dB to 42dB gain, 14-bit 40MHz analog-to-digital converter (ADC), black level clamp, and more.
The AD9972 from Analog Devices is a highly integrated dual‑channel CCD signal processor designed for high‑speed digital video camera applications. Each channel features a 1.8 V analog and digital core supply, correlated double sampler with selectable gain, a 10‑bit variable gain amplifier, a 14‑bit 40 MHz ADC, black‑level clamp, and a precision timing core with 400 ps resolution.
The device includes on‑chip 3 V horizontal and RG drivers, a 3‑wire serial interface for programming, and is offered in a compact 9 mm × 9 mm CSP‑BGA package. It operates from –25 °C to +85 °C and is targeted at professional HDTV camcorders, high‑end digital cameras, broadcast cameras, and industrial high‑speed cameras.
