AD9995KCPZRL

Overview

The AD9995KCPZRL is a 12-bit CCD signal processor featuring an integrated analog front end and Precision Timing generator. It supports pixel rates up to 36 MHz with a 12-bit A/D converter, Correlated Double Sampler (CDS), and a Variable Gain Amplifier (VGA) offering 6 dB to 42 dB gain range. The device includes on-chip drivers for horizontal clocks and reset gate, supporting 2-phase and 4-phase H-clock modes. It operates on multiple 2.7 V to 3.6 V supplies, dissipates 360 mW at maximum clock rate, and functions within a temperature range of –20°C to +85°C in a 56-lead LFCSP package.

Feature Summary

• Integrates a complete analog front end with black level clamping, CDS, VGA, and 12-bit ADC.
• Features a Precision Timing core capable of generating high-speed CCD clocks with less than 600 ps resolution.
• Includes on-chip output drivers for RG and H1–H4 clocks to directly interface with CCD sensors.
• Supports programmable electronic and mechanical shutter control via MSHUT and STROBE outputs.

Applications

• Digital still cameras
• Digital video camcorders
• Industrial imaging systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm the specific KCPZRL suffix indicates the reel packaging variant. Check for obsolete status notifications as the datasheet revision is marked obsolete. Ensure supply chain integrity to avoid counterfeit components affecting image processing performance.

Selection Notes

Select this component when designing systems requiring a highly integrated CCD interface with precise timing control. Ensure the target CCD sensor matches the supported voltage levels and clock frequencies. Verify that the system microprocessor can support the required 3-wire serial interface configuration. Consider thermal management requirements given the power dissipation characteristics at maximum operating speeds.

Part Context

The AD9995 belongs to Analog Devices' family of CCD signal processors designed for consumer and industrial imaging. It replaces discrete solutions by combining signal conditioning and timing generation into a single chip. The KCPZRL designation specifies the commercial temperature range and tape-and-reel packaging format for automated assembly processes.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet revision is marked obsolete; consult Analog Devices for current product lifecycle status and potential next-generation replacements.
