Parameter Comparison

Engineering Selection Recommendations

The AD620ANZ is a direct substitute for the XR620AIDP8 based on the following engineering criteria:

Mechanical Equivalence: The AD620ANZ maintains identical package geometry (8-DIP, 0.300" spacing) and through-hole mounting configuration, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: Both devices operate within the identical supply voltage range (4.6V to 36V) and temperature range (-40°C to 85°C). Critical parameters including slew rate (1.2V/µs) and input bias current (500 pA) are matched, ensuring functional equivalence in existing circuit designs.

Performance Enhancement: The AD620ANZ provides superior performance characteristics: reduced input offset voltage (30 µV versus 125 µV), lower supply current consumption (900 µA versus 1.3 mA), and extended bandwidth (1 MHz versus 700 kHz). These improvements maintain backward compatibility while offering enhanced signal fidelity and reduced power dissipation.

Regulatory Compliance: Both devices share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. The AD620ANZ carries ROHS3 compliance certification and REACH unaffected status, meeting modern environmental and regulatory requirements.

Product Availability: The XR620AIDP8 is classified as obsolete. The AD620ANZ maintains active product status with substantial inventory availability (29,249 units), ensuring long-term supply chain continuity and design support.

Frequently Asked Questions (FAQ)

Q: Can the AD620ANZ be used as a direct replacement for the XR620AIDP8 in existing designs?

A: Yes. The AD620ANZ is mechanically and electrically compatible with the XR620AIDP8. Both devices share identical package geometry (8-DIP), pin configuration, supply voltage range (4.6V to 36V), operating temperature range (-40°C to 85°C), and critical performance parameters (slew rate 1.2V/µs, input bias current 500 pA). No circuit modifications or PCB redesign are required.

Q: What are the key performance differences between these devices?

A: The AD620ANZ provides three measurable improvements: input offset voltage is reduced from 125 µV to 30 µV, supply current consumption decreases from 1.3 mA to 900 µA, and bandwidth increases from 700 kHz to 1 MHz. These enhancements represent performance gains that maintain full backward compatibility.

Q: Are there any compliance or certification differences?

A: The AD620ANZ carries ROHS3 compliance and REACH unaffected status, while the XR620AIDP8 compliance information is not specified. Both devices share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications for export control purposes.

Q: Why is the XR620AIDP8 marked as obsolete?

A: The XR620AIDP8 is classified as obsolete by the manufacturer. The AD620ANZ, maintained in active product status by Analog Devices Inc., is the recommended path for design continuity and future production support.

Q: What is the difference between a general purpose amplifier and an instrumentation amplifier?

A: The XR620AIDP8 is classified as a general purpose amplifier, while the AD620ANZ is classified as an instrumentation amplifier. Despite this classification difference, both devices operate within identical electrical parameters and package specifications, making them functionally interchangeable in applications requiring the specified performance envelope.

Q: Is the 8-DIP package still widely supported?

A: Yes. The 8-DIP (0.300", 7.62mm) through-hole package remains standard for linear amplifier applications. Both the XR620AIDP8 and AD620ANZ utilize this established package format, ensuring compatibility with existing PCB designs and manufacturing processes.

Q: What inventory status should be considered for production planning?

A: The XR620AIDP8 has 5,108 units in stock but is obsolete. The AD620ANZ has 29,249 units in stock and maintains active product status. For new production and long-term supply chain planning, the AD620ANZ is the recommended selection.
