Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8672ARMZ-R2 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is functional and pin-level compatibility, which requires identical specifications for amplifier type, circuit count, gain bandwidth product, slew rate, input bias current, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and package configuration.

The AD8672ARMZ-REEL qualifies as a direct substitute based on the following key parameters:

• Identical amplifier type (General Purpose)
• Identical number of circuits (2)
• Identical gain bandwidth product (10 MHz)
• Identical slew rate (4 V/µs)
• Identical input bias current (3 nA)
• Identical input offset voltage (20 µV)
• Identical supply current per channel (3 mA)
• Identical output current per channel (20 mA)
• Identical supply voltage range (10 V to 36 V)
• Identical operating temperature range (-40°C to 125°C)
• Identical package and case (8-MSOP, 0.118", 3.00mm Width)
• Identical mounting type (Surface Mount)
• Identical moisture sensitivity level (1 - Unlimited)

The distinction between these parts lies in packaging format and product status, not in electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the AD8672ARMZ-REEL be used as a direct replacement for the AD8672ARMZ-R2 in existing designs?

A: Yes. The AD8672ARMZ-REEL is electrically and mechanically identical to the AD8672ARMZ-R2. All electrical parameters, pin assignments, and package dimensions are equivalent. No circuit modifications or PCB redesign is required.

Q: What is the difference between the AD8672ARMZ-R2 and AD8672ARMZ-REEL?

A: The primary differences are product status and packaging format. The AD8672ARMZ-R2 is obsolete, while the AD8672ARMZ-REEL is active. The AD8672ARMZ-REEL is supplied in Cut Tape (CT) and Digi-Reel® formats, whereas the AD8672ARMZ-R2 uses standard packaging. All electrical and mechanical specifications are identical.

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

A: The AD8672ARMZ-REEL is certified as ROHS3 Compliant and REACH Unaffected. The AD8672ARMZ-R2 does not specify these certifications. For applications requiring regulatory compliance documentation, the AD8672ARMZ-REEL is the appropriate choice.

Q: Will the AD8672ARMZ-REEL work with the same PCB footprint as the AD8672ARMZ-R2?

A: Yes. Both parts use the 8-MSOP package with identical dimensions (0.118" width, 3.00mm). PCB footprints, land patterns, and assembly processes are directly compatible without modification.

Q: What is the supply availability for the AD8672ARMZ-REEL?

A: The AD8672ARMZ-REEL has 20,750 pieces in current inventory, indicating strong supply availability. The AD8672ARMZ-R2, being obsolete, has limited remaining stock (1,016 pieces).

Q: Are the electrical performance characteristics identical between these parts?

A: Yes. Both parts have identical gain bandwidth product (10 MHz), slew rate (4 V/µs), input bias current (3 nA), input offset voltage (20 µV), supply current (3 mA per channel), output current (20 mA per channel), supply voltage range (10 V to 36 V), and operating temperature range (-40°C to 125°C).

Q: Can I mix AD8672ARMZ-R2 and AD8672ARMZ-REEL parts in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably in the same design and production environment. However, transitioning to the AD8672ARMZ-REEL is recommended for long-term supply chain stability.
