AD9824KCPZ

Overview

The AD9824KCPZ is a complete analog signal processor for CCD applications, featuring a 30 MHz single-channel architecture designed to sample and condition outputs of interlaced and progressive scan area CCD arrays. The signal chain includes an input clamp, correlated double sampler (CDS), Pixel Gain Amplifier (PxGA), digitally controlled Variable Gain Amplifier (VGA), black level clamp, and a 14-bit A/D converter. It operates from a single 3 V power supply with typical power consumption of 153 mW at 3 V. The device supports a maximum clock rate of 30 MHz and provides a full-scale input voltage of 2.0 V. It is housed in a space-saving 48-lead LFCSP package.

Feature Summary

• Integrates a 14-bit ADC with a 30 MSPS Correlated Double Sampler (CDS) for high-speed signal conditioning.
• Features a programmable Pixel Gain Amplifier (PxGA) with six-bit resolution for color steering and white balance adjustment.
• Includes a digitally controlled Variable Gain Amplifier (VGA) offering a gain range from 2 dB to 36 dB.
• Utilizes a low-noise input clamp circuit and optical black clamp loop to remove DC offsets and track black level variations.

Applications

• High Performance Digital Still Cameras
• Industrial/Scientific Imaging

Procurement Notes

Verify the specific suffix KCPZ against the manufacturer's current ordering guide to confirm the temperature range and package option. Confirm RoHS compliance status through official documentation. Check for any End-of-Life notices or production changes via the manufacturer's Product Change Notification service before finalizing procurement plans.

Selection Notes

Select this component when processing signals from interlaced or progressive scan CCD arrays requiring integrated signal conditioning. Ensure the system design accommodates a single 3 V supply and utilizes a 3-wire serial interface for register configuration. Verify that the 48-lead LFCSP package fits the PCB layout constraints and thermal requirements.

Part Context

The AD9824KCPZ belongs to the AD9824 family of CCD signal processors manufactured by Analog Devices. This series is engineered specifically for imaging applications where high-resolution analog-to-digital conversion and precise signal conditioning are required directly from the sensor output.

Replacement Considerations

Consult the manufacturer's datasheet for a list of similar parts. Verify pin compatibility and electrical specifications if substituting with other models in the AD9824 series or related CCD signal processor families.
