Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD829AR is determined by electrical and mechanical parameter equivalence. The primary substitute, AD829ARZ, maintains identical electrical specifications across all critical performance metrics: -3dB bandwidth of 120 MHz, slew rate of 230 V/µs, supply current of 5.3 mA, output current per channel of 32 mA, and supply voltage range of ±4.5V to ±18V. Both components utilize the same 8-SOIC surface mount package with 0.154" (3.90mm) width, ensuring mechanical compatibility in existing PCB layouts.

The substitution is valid based on the following key parameters:

• Identical -3dB bandwidth specification
• Identical slew rate specification
• Identical supply current specification
• Identical output current specification
• Identical supply voltage range
• Identical package and pinout configuration
• Identical number of circuits (single amplifier)
• Identical moisture sensitivity level

Engineering Selection Recommendations

The AD829ARZ is the direct substitute for the AD829AR based on complete electrical and mechanical parameter equivalence. The AD829ARZ is currently in active production status, whereas the AD829AR is obsolete. This transition from obsolete to active status makes the AD829ARZ the appropriate selection for new designs and ongoing procurement.

The AD829ARZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. The component is supplied in tube packaging, which differs from the unspecified packaging of the AD829AR but does not affect electrical or mechanical compatibility.

All critical performance parameters remain identical between the two parts, including bandwidth, slew rate, supply current, output current, and supply voltage specifications. The 8-SOIC package configuration ensures direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the AD829ARZ be used as a direct replacement for the AD829AR in existing designs?

A: Yes. The AD829ARZ is electrically and mechanically equivalent to the AD829AR. All performance specifications, including -3dB bandwidth, slew rate, supply current, output current, and supply voltage range, are identical. The 8-SOIC package pinout and dimensions are the same, enabling direct substitution without circuit modification.

Q: Why is the AD829AR listed as obsolete?

A: The AD829AR has reached end-of-life status in Analog Devices' product portfolio. The AD829ARZ, which shares identical electrical and mechanical specifications, is the active equivalent and is the recommended component for procurement and new designs.

Q: Are there any compliance differences between the AD829AR and AD829ARZ?

A: The AD829ARZ carries ROHS3 compliance and REACH unaffected status. These certifications apply to the active part. Both components share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: What is the difference in packaging between these parts?

A: The AD829ARZ is supplied in tube packaging, while the AD829AR packaging specification is not provided in the technical data. This difference does not affect the electrical performance or PCB-level compatibility of the component.

Q: Are the pin configurations identical between AD829AR and AD829ARZ?

A: Yes. Both parts use the 8-SOIC package with identical pinout. The package dimensions are 0.154" (3.90mm) width for both components, ensuring mechanical compatibility in existing PCB layouts.

Q: What is the moisture sensitivity level for these components?

A: Both the AD829AR and AD829ARZ have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited moisture sensitivity tolerance. No special moisture control measures are required during storage or handling.

Q: Can the AD829ARZ be used in high-frequency video amplification applications?

A: Yes. The AD829ARZ maintains the 120 MHz -3dB bandwidth and 230 V/µs slew rate specifications required for video amplification applications. The component is suitable for voltage feedback amplifier configurations in video signal processing circuits.
