Overview
The AD9841AJSTRL is a complete analog signal processor for CCD applications, featuring a 20 MHz single-channel architecture. It includes an input clamp, correlated double sampler (CDS), Pixel Gain Amplifier (PxGA), variable gain amplifier (VGA), and a 10-bit A/D converter. The device operates from a single 3 V supply, typically dissipating 78 mW in normal operation. It supports a maximum clock rate of 20 MHz and utilizes a 3-wire serial digital interface for register programming. The component is housed in a 48-lead LQFP package.
Feature Summary
- Integrates a 20 MSPS Correlated Double Sampler (CDS) with low noise clamp circuits.
- Includes a programmable 6-Bit Pixel Gain Amplifier (PxGA) for color steering.
- Features a digitally controlled Variable Gain Amplifier (VGA) with a wide gain range.
- Provides auxiliary inputs with dedicated VGA and input clamp capabilities.
Applications
- Digital Still Cameras
- Digital Video Camcorders
Procurement Notes
Verify the specific ordering suffix to confirm the reel packaging format and ensure compliance with RoHS directives if required by your manufacturing standards. Confirm that the operating temperature range meets your system's environmental specifications before finalizing procurement.
Selection Notes
Select this model over the AD9842A variant when a 10-bit resolution is sufficient for the application. Ensure the design accommodates the 48-lead LQFP footprint and provides adequate thermal management for the specified power dissipation levels under continuous operation.
Part Context
This component belongs to the AD9841A/AD9842A family of complete CCD signal processors manufactured by Analog Devices Inc. These devices are designed to sample and condition outputs from interlaced and progressive scan area CCD arrays, offering a comprehensive solution for image sensor signal processing.
Replacement Considerations
The AD9842AJSTRL serves as a direct pin-compatible alternative within the same series, differing primarily in its 12-bit ADC resolution compared to the 10-bit resolution of the AD9841AJSTRL.
