AD9847AKCPZRL

Overview

The AD9847AKCPZRL is a 10-bit CCD signal processor with an integrated timing driver, designed for digital still camera applications. It operates at pixel rates up to 40 MHz and features a complete analog front end including CDS, PxGA, VGA, black level clamp, and a 10-bit A/D converter. The device includes a Precision Timing core with 500 ps resolution at 40 MSPS. It supports on-chip 5 V horizontal and RG drivers and is controlled via a 3-wire serial interface. The component is housed in a 48-lead LQFP package and functions within an operating temperature range of –20°C to +85°C.

Feature Summary

• Integrated Correlated Double Sampler (CDS) and Pixel Gain Amplifier (PxGA)
• Precision Timing Core providing high-speed clock adjustment
• On-chip 5 V Horizontal and Reset Gate (RG) Drivers
• Programmable Variable Gain Amplifier (VGA) with wide dynamic range

Applications

• Digital Still Cameras

Procurement Notes

Verify the specific suffix 'RL' against the official Analog Devices ordering guide to confirm reel packaging status. Ensure the part number matches the exact temperature grade and package variant required for the design. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Selection Notes

Select this component for systems requiring a highly integrated CCD signal processing solution with minimal external components. The built-in timing driver reduces board space by eliminating external clock buffers. Verify that the target CCD sensor operates within the supported 40 MHz pixel rate limit and voltage requirements.

Part Context

This part belongs to the AD9847 family of CCD signal processors from Analog Devices. It combines analog front-end processing with precise digital timing generation in a single package. The device simplifies the design of digital imaging systems by integrating essential signal conditioning and CCD drive capabilities.

Replacement Considerations

The AD9847AKST is a compatible alternative in the same family, offering identical functionality but packaged in a Thin Plastic Quad Flatpack (LQFP) instead of the standard LQFP.
