AD8625AR Equivalent & Substitute Parts

Part Overview

The AD8625AR is a J-FET operational amplifier manufactured by Analog Devices Inc., configured as a 4-circuit rail-to-rail amplifier in a 14-SOIC surface mount package. This device is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. The AD8625AR delivers precision amplification with extremely low input bias current and stable performance across industrial temperature ranges.

Substitute Part Grouping Explanation

Substitution of the AD8625AR is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is functional and pin-level compatibility within the same package footprint and electrical specification envelope.

The AD8625AR qualifies for direct substitution with the AD8625ARZ based on the following parameters:

• Identical amplifier topology (J-FET, 4-circuit configuration)
• Identical output architecture (rail-to-rail)
• Identical electrical performance specifications (slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability)
• Identical supply voltage range (5 V to 26 V)
• Identical operating temperature range (-40°C to 85°C)
• Identical package and pinout (14-SOIC, 0.154" width, 3.90mm)
• Identical surface mount mounting type
• Identical moisture sensitivity classification (MSL 1)

Engineering Selection Recommendations

The AD8625ARZ is the direct functional equivalent of the AD8625AR and serves as the primary substitute for applications requiring the AD8625AR. Selection of the AD8625ARZ is based on the following engineering criteria:

Product Status: The AD8625AR is classified as obsolete, while the AD8625ARZ maintains active product status. This distinction is critical for long-term supply chain continuity and design longevity.

Regulatory Compliance: The AD8625ARZ carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The AD8625AR does not specify these compliance certifications.

Electrical and Mechanical Equivalence: All electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capability, are identical between the two devices. The package footprint, pinout, and mounting type are identical, enabling direct board-level substitution without design modification.

Packaging Consideration: The AD8625ARZ is supplied in tube packaging, whereas the AD8625AR packaging type is not specified. This difference does not affect electrical performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AD8625ARZ be used as a direct replacement for the AD8625AR in existing designs?

A: Yes. The AD8625ARZ is electrically and mechanically equivalent to the AD8625AR. All electrical specifications, package dimensions, pinout, and operating parameters are identical. No design modifications are required for substitution.

Q: What is the primary reason for substituting the AD8625AR?

A: The AD8625AR is classified as obsolete. The AD8625ARZ is the active equivalent component from Analog Devices Inc. and is recommended for new designs and ongoing production to ensure supply chain continuity.

Q: Are there differences in the 14-SOIC package between the two parts?

A: No. Both the AD8625AR and AD8625ARZ use the identical 14-SOIC package with 0.154" width and 3.90mm dimensions. The package footprint and pinout are fully compatible.

Q: Does the AD8625ARZ meet current environmental regulations?

A: Yes. The AD8625ARZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the difference between the tube and unspecified packaging?

A: The AD8625ARZ is supplied in tube packaging for automated assembly processes. The AD8625AR packaging type is not specified in the component data. This difference affects only the delivery format and does not impact electrical performance or board-level compatibility.

Q: Are the electrical performance characteristics identical between AD8625AR and AD8625ARZ?

A: Yes. Both devices share identical specifications for slew rate (5 V/µs), gain bandwidth product (5 MHz), input bias current (0.25 pA), input offset voltage (350 µV), supply current (710 µA across 4 channels), output current per channel (15 mA), and operating temperature range (-40°C to 85°C).

Q: Can the AD8625ARZ be used in applications requiring the full -40°C to 85°C operating temperature range?

A: Yes. The AD8625ARZ is rated for the full -40°C to 85°C operating temperature range, identical to the AD8625AR.
