AD9846AJSTRL

Overview

The AD9846AJSTRL is a complete analog signal processor for CCD applications, featuring a 30 MHz single-channel architecture. It includes a 10-bit A/D converter with a maximum clock rate of 30 MHz and a full-scale input voltage of 2.0 V. The device operates from a single 3 V supply (2.7 V to 3.6 V) and dissipates 117 mW in normal operation. Key specifications include a differential nonlinearity of ±1.0 LSB and no missing codes guaranteed at 10-bit resolution. It is housed in a 48-lead LQFP package.

Feature Summary

• Integrates a 30 MSPS correlated double sampler (CDS), Pixel Gain Amplifier (PxGA), variable gain amplifier (VGA), and 10-bit A/D converter.
• Features a 3-wire serial digital interface for programmable gain adjustment, black level control, and power-down modes.
• Supports multiple color steering modes including Mosaic Separate, Interlace, and 3-Color configurations via the PxGA.

Applications

• Digital Still Cameras
• Digital Video Camcorders
• Industrial Imaging

Procurement Notes

Verify the specific ordering suffix JSTRL against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with 3 V single-supply logic levels and check for ESD sensitivity precautions during handling. Confirm that the 48-lead LQFP thermal characteristics meet system requirements.

Selection Notes

Select this component when processing interlaced or progressive scan area CCD arrays requiring integrated signal conditioning. The device is suitable for designs needing a single-chip solution for CDS, VGA, and ADC functions. Consider the 30 MHz maximum clock rate and 117 mW power consumption for system planning.

Part Context

The AD9846A is part of Analog Devices' CCD signal processor family designed for consumer imaging applications. It consolidates multiple analog stages into a single chip to reduce board space and complexity. The AJSTRL variant specifically denotes the -20°C to +85°C operating range and the 48-lead LQFP package option.
