Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8065AR is determined by electrical and mechanical parameter equivalence within the voltage feedback amplifier category. The primary substitution criteria include:

Electrical Parameters:

• Amplifier topology (voltage feedback architecture)
• Single circuit configuration
• Rail-to-rail output capability
• Slew rate of 180V/µs
• -3dB bandwidth of 145 MHz
• Input bias current of 3 pA
• Input offset voltage of 400 µV
• Supply current of 6.6 mA
• Output current per channel of 30 mA
• Supply voltage range of 5V to 24V
• Operating temperature range of -40°C to 85°C

Mechanical Parameters:

• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Moisture sensitivity level 1 (unlimited)

The AD8065ARZ qualifies as a direct substitute based on identical electrical specifications and package configuration. The distinction between these parts is limited to packaging format (tube versus unspecified) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The AD8065ARZ is the direct equivalent substitute for the AD8065AR. Both components share identical electrical and mechanical specifications across all critical parameters. The AD8065ARZ is the preferred selection for new designs and procurement due to its active product status with Analog Devices Inc.

The AD8065ARZ carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for applications subject to environmental and hazardous substance restrictions. The obsolete status of the AD8065AR indicates that Analog Devices Inc. no longer manufactures this variant, making the AD8065ARZ the appropriate long-term solution for component sourcing.

Both parts are manufactured by Analog Devices Inc. within the FastFET™ series and maintain identical performance characteristics, ensuring functional interchangeability in circuit applications. The packaging format difference (tube for AD8065ARZ) does not affect electrical performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AD8065ARZ directly replace the AD8065AR in existing designs?

A: Yes. The AD8065ARZ is electrically and mechanically identical to the AD8065AR. All electrical parameters, including slew rate, bandwidth, input bias current, offset voltage, supply current, output current, and operating temperature range are equivalent. The 8-SOIC surface mount package dimensions are identical, enabling direct PCB substitution without design modification.

Q: What is the primary difference between AD8065AR and AD8065ARZ?

A: The primary differences are product status and packaging format. The AD8065AR is obsolete, while the AD8065ARZ is active. The AD8065ARZ is supplied in tube packaging, whereas the AD8065AR packaging format is not specified. These differences do not affect electrical performance or circuit functionality.

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

A: The AD8065ARZ carries ROHS3 compliance and REACH unaffected status. The AD8065AR compliance status is not specified. For applications requiring environmental compliance documentation, the AD8065ARZ provides explicit regulatory alignment.

Q: Is the 8-SOIC package compatible with standard PCB assembly equipment?

A: Yes. Both the AD8065AR and AD8065ARZ use the 8-SOIC (0.154", 3.90mm width) surface mount package, which is compatible with standard automated PCB assembly processes. No special handling or equipment modifications are required.

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