AD9948AKCPZ

Overview

The AD9948AKCPZ is a 10-bit CCD signal processor manufactured by Analog Devices Inc. It integrates an analog front end with A/D conversion and a programmable timing driver, specified for pixel rates up to 36 MHz. The device features a Precision Timing core with less than 600 ps resolution, a correlated double sampler (CDS), and a variable gain amplifier (VGA) offering 6 dB to 42 dB gain. It operates on a single 3 V supply and is housed in a 40-lead LFCSP package.

Feature Summary

• Integrates a complete analog front end with 10-bit ADC and programmable timing driver
• Includes Precision Timing core for high-speed clock adjustment with sub-nanosecond resolution
• Features on-chip correlated double sampling and variable gain amplification

Applications

• Digital still cameras
• High speed digital imaging applications

Procurement Notes

Verify the specific revision status and RoHS compliance details directly from the manufacturer's datasheet before procurement. Confirm that the 40-lead LFCSP package matches the target PCB footprint requirements. Ensure the single 3 V power supply constraint aligns with the system design constraints.

Selection Notes

Select this component when a highly integrated solution for CCD sensors is required within compact form factors. It is suitable for designs needing precise timing control and onboard signal conditioning without external discrete components. Consider the 10-bit resolution limit when evaluating dynamic range requirements against higher-resolution alternatives like the AD9949 series.

Part Context

This part belongs to the AD994x family of CCD signal processors from Analog Devices. It serves as a mid-range option between lower-resolution predecessors and higher-end models like the AD9949, which supports larger line lengths. The AKCPZ suffix indicates the specific lead-free tape and reel packaging variant.

Replacement Considerations

The AD9949AKCPZ offers similar functionality with support for CCD line lengths exceeding 4096 pixels. Designers requiring higher resolution or extended line capabilities may consider this alternative, though pin compatibility and software configuration differences must be evaluated.
