The AD9844AJST from Analog Devices is a comprehensive analog signal processor designed for CCD applications. It is engineered to sample and condition outputs from interlaced and progressive scan area CCD arrays. The signal chain includes an input clamp, correlated double sampler (CDS), digitally controlled variable gain amplifier (VGA), black level clamp, and a 12-bit Analog-to-Digital Converter (ADC).
This processor supports a 20 MSPS sampling rate and features a 12-bit resolution ADC. It offers a variable gain amplifier with a range of 2 dB to 36 dB and a CDS gain with 6-bit resolution from 4 dB to 6 dB. The device operates from a single 3V power supply, typically consuming 65 mW at 2.7V.
Programmable features are accessible via a 3-wire serial digital interface, allowing adjustments for gain, black level, input configuration, and power-down modes. The AD9844AJST is housed in a 48-lead LQFP package, making it suitable for space-constrained designs.
Applications for the AD9844AJST include digital still cameras, digital video camcorders, and PC cameras, where precise analog signal conditioning is critical for image quality.
