The AD9840AJST is an electronic component that belongs to the product category of Sensor and Detector Interfaces. This complete analog signal processor is designed for CCD applications and features a 40 MHz single-channel architecture. It can sample and condition the outputs of interlaced and progressive scan area CCD arrays, and its signal chain includes an input clamp, correlated double sampler (CDS), digitally controlled variable gain amplifier (VGA), black level clamp, and 10-bit A/D converter. Moreover, it provides additional input modes for processing analog video signals.

• 40 MSPS Correlated Double Sampler (CDS)
• 4 dB ± 6 dB Variable CDS Gain with 6-Bit Resolution
• 2 dB to 36 dB 10-Bit Variable Gain Amplifier (VGA)
• Low Noise Clamp Circuits
• Analog Preblanking Function
• 10-Bit 40 MSPS A/D Converter
• Auxiliary Inputs with VGA and Input Clamp
• 3-Wire Serial Digital Interface
• 3 V Single Supply Operation
• Low Power: 155 mW @ 3.0 V Supply
• 48-Lead LQFP Package

The AD9840AJST is mainly used in CCD applications, such as digital video camcorders, digital still cameras, and industrial imaging.

The AD9840AJST features a complete analog signal processor designed for CCD applications. It can process the output of interlaced and progressive scan area CCD arrays, with low noise clamp circuits and auxiliary inputs with VGA and input clamp. In addition, it supports low power operation and has a compact size with a 48-Lead LQFP package.

The AD9840AJST does not provide a wide operating voltage range, as it only operates at 3 V single supply. Moreover, its designed use only applies to CCD-related systems, so it cannot be used outside this field.
