AD9948KCPZ Equivalent & Substitute Parts

Part Overview

The AD9948KCPZ is a 10-bit CCD signal processor manufactured by Analog Devices Inc., designed for interface applications requiring CCD image sensor signal conditioning and processing. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The AD9948KCPZ operates across the industrial temperature range of -20°C to 85°C and is housed in a 40-LFCSP (6x6) surface mount package with exposed pad configuration.

Substitute Part Grouping Explanation

Substitution of the AD9948KCPZ is determined by compatibility across the following critical parameters:

Package Compatibility: Both main and substitute parts must use the 40-LFCSP (6x6) surface mount package with exposed pad configuration to ensure PCB layout and thermal management compatibility.
Interface Category: All parts must function within the Interface category for CCD signal processing applications.
Input/Output Type: Logic-level input and output compatibility is required for system integration.
Operating Temperature Range: The -20°C to 85°C operating range must be maintained or exceeded.
Moisture Sensitivity: MSL 3 rating (168 hours) establishes handling and storage requirements.
Manufacturer Consistency: Analog Devices Inc. maintains design and quality standards across the product line.

The AD9949KCPZ qualifies as a substitute based on these parameters, with the primary functional difference being a 12-bit resolution versus the 10-bit resolution of the AD9948KCPZ.

Engineering Selection Recommendations

The AD9949KCPZ is available as an active product from Analog Devices Inc., providing supply continuity for applications currently using the obsolete AD9948KCPZ. Both devices share identical package specifications, operating temperature ranges, and moisture sensitivity ratings, ensuring mechanical and thermal compatibility in existing PCB designs.

The AD9949KCPZ offers 12-bit resolution compared to the 10-bit resolution of the AD9948KCPZ. This increased resolution capability provides enhanced signal fidelity for CCD signal processing applications. The substitute part maintains full compliance with EAR99 export classification and operates within the same industrial temperature specification.

Selection between these parts should be based on application requirements for signal resolution and the availability of the active AD9949KCPZ versus the obsolete AD9948KCPZ.

Frequently Asked Questions (FAQ)

Q: Can the AD9949KCPZ directly replace the AD9948KCPZ in existing designs?

A: The AD9949KCPZ is mechanically and thermally compatible with the AD9948KCPZ due to identical package specifications (40-LFCSP 6x6), operating temperature range (-20°C to 85°C), and moisture sensitivity rating (MSL 3). The primary difference is the 12-bit versus 10-bit resolution. Functional compatibility depends on whether the application can accommodate the increased resolution output.

Q: What is the significance of the package designation 40-LFCSP (6x6)?

A: The 40-LFCSP (6x6) package is a 40-pin low-profile fine-pitch chip-scale package with 6mm x 6mm dimensions and an exposed pad for thermal management. This package specification is identical between the AD9948KCPZ and AD9949KCPZ, ensuring PCB layout compatibility and thermal performance characteristics remain unchanged.

Q: Why is the AD9948KCPZ classified as obsolete?

A: The AD9948KCPZ is listed as obsolete by Analog Devices Inc., indicating the manufacturer has discontinued production. The active AD9949KCPZ serves as the current product offering for CCD signal processing applications in this product family.

Q: Are there compliance or certification differences between these parts?

A: Both parts share identical ECCN classification (EAR99) and moisture sensitivity level (MSL 3, 168 hours). The AD9949KCPZ includes RoHS3 compliance and REACH unaffected status, providing additional regulatory documentation for new designs.

Q: What is the primary functional difference between these devices?

A: The AD9948KCPZ provides 10-bit CCD signal processing, while the AD9949KCPZ provides 12-bit CCD signal processing. The 12-bit resolution of the substitute part offers increased signal precision and dynamic range for image sensor applications.
