Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7247JR is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion
• Channel Count: Dual D/A converters
• Output Configuration: Voltage-buffered topology
• Interface Protocol: Parallel data input
• Reference Architecture: Support for external and internal references
• Supply Voltage Requirements: ±15V analog, 15V digital
• Package Specification: 24-SOIC form factor with identical pinout
• Thermal Range: -40°C to 85°C operating window
• Electrical Performance: INL/DNL specifications and 10µs settling time

The AD7247JR substitute must maintain identical electrical characteristics, pinout compatibility, and functional behavior to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The AD7247JRZ is the direct functional equivalent of the AD7247JR. Both components share identical electrical specifications, pinout configuration, and performance characteristics across all critical parameters. The primary distinction is product lifecycle status: the AD7247JR is obsolete, while the AD7247JRZ maintains active production status.

The AD7247JRZ provides additional compliance advantages, including ROHS3 certification and REACH compliance documentation, making it the preferred selection for new designs and production continuity. The component is available in tube packaging and maintains full backward compatibility with existing AD7247JR circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the AD7247JRZ directly replace the AD7247JR without circuit modification?

A: Yes. The AD7247JRZ is a direct pin-for-pin and functionally equivalent substitute. All electrical parameters, supply voltage requirements, output characteristics, and timing specifications are identical. No circuit redesign is required.

Q: What is the difference between AD7247JR and AD7247JRZ?

A: The components are electrically and functionally identical. The primary differences are product status (AD7247JR is obsolete; AD7247JRZ is active) and packaging format (AD7247JRZ is supplied in tube packaging). The AD7247JRZ includes ROHS3 and REACH compliance certifications.

Q: Are there any compatibility concerns with the 24-SOIC package?

A: No. Both parts use the identical 24-SOIC (0.295", 7.50mm width) package with matching pinout. PCB footprints and assembly processes remain unchanged.

Q: What supply voltages are required for operation?

A: Both components require ±15V for analog supply and 15V for digital supply. Ensure your power distribution network supports these voltage levels.

Q: Is the AD7247JRZ suitable for applications requiring ROHS and REACH compliance?

A: Yes. The AD7247JRZ is ROHS3 compliant and REACH unaffected, making it appropriate for applications with environmental and regulatory compliance requirements.

Q: What is the settling time specification?

A: Both the AD7247JR and AD7247JRZ have a settling time of 10µs, ensuring consistent timing performance in data acquisition applications.
