AD8079AR Equivalent & Substitute Parts

Part Overview

The AD8079AR is a dual-channel buffer amplifier integrated circuit manufactured by Analog Devices Inc. in 8-SOIC surface mount packaging. This device functions as a high-speed buffer with dual independent circuits, designed for signal conditioning and impedance matching applications. The AD8079AR is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The substitute part maintains identical electrical performance and mechanical compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the AD8079AR with the AD8079ARZ is based on strict equivalence across all electrical and mechanical parameters. Both parts share the same base product number (AD8079) and are manufactured by Analog Devices Inc. The substitution is valid because:

Electrical Parameter Equivalence: All electrical specifications are identical, including slew rate (800 V/µs), bandwidth (260 MHz), input bias current (3 µA), input offset voltage (10 mV), supply current (10 mA per channel), output current (70 mA per channel), and supply voltage range (6 V to 12 V).

Mechanical and Thermal Equivalence: Both parts utilize identical 8-SOIC surface mount packaging with 0.154" width (3.90 mm). Operating temperature range is identical (-40°C to 85°C). Moisture sensitivity level is identical (MSL 1 - Unlimited).

Functional Equivalence: Both parts are dual-channel buffer amplifiers with identical circuit count and output characteristics.

The primary distinction is product status: AD8079AR is obsolete, while AD8079ARZ is active. Packaging format differs (AD8079AR unspecified versus AD8079ARZ in Tube), but this does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AD8079ARZ is the direct equivalent substitute for the AD8079AR. Selection of AD8079ARZ is appropriate for the following reasons:

Product Status Consideration: The AD8079AR is classified as obsolete, indicating discontinued manufacturing and limited future availability. The AD8079ARZ maintains active product status, ensuring continued supply and manufacturer support.

Compliance and Certification: The AD8079ARZ carries RoHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Electrical and Mechanical Compatibility: Complete parameter equivalence across all electrical specifications, thermal characteristics, and mechanical dimensions ensures direct substitution without circuit redesign or board layout modification.

Inventory and Availability: The AD8079ARZ demonstrates higher inventory availability (2752 Pcs) compared to the AD8079AR (2200 Pcs), supporting production continuity and supply chain reliability.
