AD9804AJSTZRL

Overview

The AD9804AJSTZRL is a complete analog signal processor for CCD applications, featuring an 18 MHz single-channel architecture designed to sample and condition outputs from interlaced and progressive scan area CCD arrays. The internal signal chain comprises an input clamp, correlated double sampler (CDS), digitally controlled variable gain amplifier (VGA) with 6 dB to 40 dB range, black level clamp, and a 10-bit A/D converter operating at 18 MSPS. It utilizes a 3-wire serial digital interface for programming the internal VGA gain register and operates on a 3 V single supply.

Feature Summary

• Integrates a low-noise input clamp circuit for effective signal conditioning
• Includes a 10-bit correlated double sampler (CDS) for noise reduction
• Features a digitally controlled variable gain amplifier with programmable gain settings
• Utilizes a 3-wire serial digital interface for configuration control

Applications

• PC cameras
• Digital still cameras

Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly. Ensure proper handling procedures are followed due to surface mount packaging requirements. Validate part markings against official datasheet specifications to prevent counterfeit risks.

Selection Notes

Select this component when designing systems requiring integrated CCD signal processing with a 10-bit resolution and 18 MHz sampling rate. Consider the 3 V single supply operation and LQFP package constraints during PCB layout. Evaluate the need for external components versus the integrated CDS and VGA functions based on system noise requirements.

Part Context

This part belongs to the AD98xx series of CCD signal processors from Analog Devices. It shares architectural similarities with other models in the family but is specifically optimized for 18 MHz operation. The 'JSTZ' suffix indicates a specific lead-free tape and reel packaging variant within the broader AD9804 product line.

Replacement Considerations

The AD9806 serves as a similar alternative within the same product family, offering comparable CCD signal processing capabilities. Designers should verify pin compatibility and electrical parameter alignment before substitution.
