AD2S90AP Equivalent & Substitute Parts

Part Overview

The AD2S90AP is a 12-bit R/D (Resolver-to-Digital) converter manufactured by Analog Devices Inc., designed for data acquisition applications requiring serial interface communication. This component features dual-channel architecture with ±4.75V to ±5.25V dual supply operation and operates across the industrial temperature range of -40°C to 85°C. The AD2S90AP is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD2S90AP is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Configuration: 12-bit resolution with 2-channel architecture
• Data Interface Protocol: Serial interface requirement
• Electrical Specifications: Dual ±4.75V to ±5.25V supply voltage compatibility
• Operating Temperature Range: -40°C to 85°C industrial specification
• Package Compatibility: 20-LCC (J-Lead) / 20-PLCC (9x9) surface mount package
• Manufacturer Consistency: Analog Devices Inc. product line

The AD2S90APZ qualifies as a direct substitute based on identical electrical, functional, and mechanical parameters. The primary distinction is product status and packaging format, with AD2S90APZ available in active production status with tube packaging.

Engineering Selection Recommendations

The AD2S90APZ is the direct functional equivalent for AD2S90AP replacement. Selection is based on the following factors:

Product Status: The AD2S90AP is classified as obsolete, while AD2S90APZ maintains active production status, ensuring long-term availability and supply chain reliability.

Compliance Certifications: AD2S90APZ carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and system updates.

Electrical and Functional Equivalence: All critical parameters—resolution, channel count, data interface, supply voltage, operating temperature, and package specifications—are identical between both parts.

Packaging Consideration: AD2S90APZ is supplied in tube packaging format, which is standard for active production components and compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can AD2S90APZ directly replace AD2S90AP in existing designs?

A: Yes. The AD2S90APZ is electrically and mechanically identical to the AD2S90AP. All functional parameters, pin configurations, voltage specifications, and operating characteristics match exactly. Direct substitution is supported without circuit modification.

Q: Why is the AD2S90AP classified as obsolete?

A: The AD2S90AP has been superseded by the AD2S90APZ in Analog Devices' product portfolio. The APZ variant is the current active production equivalent and is recommended for all new designs and component procurement.

Q: Are there differences in RoHS or REACH compliance between the two parts?

A: The AD2S90APZ is certified ROHS3 compliant and REACH unaffected. The AD2S90AP compliance status is not specified in available documentation. For applications requiring environmental compliance certification, AD2S90APZ is the appropriate selection.

Q: What is the difference between the packaging formats?

A: The AD2S90AP packaging format is not specified. The AD2S90APZ is supplied in tube packaging, which is standard for surface mount components and compatible with pick-and-place assembly equipment.

Q: Are the 20-PLCC (9x9) and 20-LCC (J-Lead) package designations equivalent?

A: Yes. Both designations refer to the same 20-pin surface mount package with J-lead configuration and 9x9mm dimensions. The parts are mechanically and electrically interchangeable at the package level.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
