AD9995KCPZ

Overview

The AD9995KCPZRL is an obsolete 12-bit CCD signal processor with a precision timing generator, manufactured by Analog Devices Inc. It operates within a temperature range of –20°C to +85°C and utilizes a 56-lead LFCSP package. The device supports a maximum clock rate (CLI) of 36 MHz and features a variable gain amplifier (VGA) with a gain range from 6 dB to 42 dB. Power supply voltages for AVDD, TCVDD, RGVDD, HVDD, DRVDD, and DVDD range from 2.7 V to 3.6 V. At 36 MHz operation with typical supply levels, power dissipation is approximately 360 mW.

Feature Summary

• Integrates a complete analog front end including correlated double sampling, black level clamping, and a 12-bit A/D converter.
• Features a Precision Timing core capable of supporting both 4-phase and 6-phase vertical clocking with sub-nanosecond resolution.
• Includes on-chip drivers for horizontal clocks (H1–H4) and reset gate (RG), eliminating the need for external buffer amplifiers.
• Provides 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 channels due to obsolete status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Review datasheet revision history for any functional updates or pinout changes. Ensure proper electrostatic discharge precautions are implemented during handling and soldering processes.

Selection Notes

Evaluate compatibility with target CCD sensor timing requirements, specifically vertical phase count and pixel clock frequency. Assess power budget constraints against specified dissipation curves at operating temperatures. Verify serial interface voltage levels match the host microprocessor logic standards. Consider thermal management solutions given the LFCSP package characteristics.

Part Context

The AD9995 belongs to the Analog Devices CCD signal processor family, designed to simplify camera system architecture by combining signal conditioning and timing generation. It serves as a direct replacement for discrete solution designs in legacy imaging equipment. The KCPZ suffix indicates a lead-free, halogen-free variant in a 56-lead LFCSP package.

Replacement Considerations

Public confirmed substitute part numbers: None available. The AD9995 is listed as obsolete with no direct cross-reference provided in official documentation.
