Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD22057R is determined by strict equivalence across the following critical parameters:

• Functional Classification: Differential amplifier, single-supply operation
• Electrical Specifications: Supply current of 200 µA, voltage input to analog output conversion
• Operating Temperature Range: -40°C to 125°C
• Package Specification: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Manufacturer: Analog Devices Inc. (same product family)
• Base Product Number: AD22057

The AD22057RZ qualifies as a direct substitute based on identical electrical performance, package geometry, and thermal operating range. The primary distinction is product status: AD22057RZ is active production, whereas AD22057R is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The AD22057RZ is the direct equivalent for the obsolete AD22057R. Selection is based on the following engineering criteria:

Product Status: The AD22057RZ maintains active production status with Analog Devices Inc., ensuring continued availability and supply chain reliability. The AD22057R, classified as obsolete, presents procurement risk for new designs and ongoing production.

Compliance and Certifications: The AD22057RZ carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in most jurisdictions. These certifications are not specified for the AD22057R.

Electrical and Mechanical Equivalence: Both parts share identical electrical specifications (200 µA supply current, -40°C to 125°C operating range) and mechanical packaging (8-SOIC, 0.154" width). Pin configuration and functional behavior are equivalent.

Packaging Format: The AD22057RZ is supplied in tube packaging, whereas the AD22057R packaging format is not specified. Both use the same 8-SOIC case geometry, ensuring PCB compatibility.

For new designs and production transitions, the AD22057RZ is the appropriate selection. For legacy system maintenance requiring the exact original part number, the AD22057R may be sourced from remaining inventory, though supply is limited.

Frequently Asked Questions (FAQ)

Q: Can the AD22057RZ be used as a direct replacement for the AD22057R in existing designs?

A: Yes. The AD22057RZ is electrically and mechanically equivalent to the AD22057R. Both devices share identical supply current (200 µA), operating temperature range (-40°C to 125°C), and 8-SOIC package geometry. Pin configuration and functional performance are equivalent, enabling direct substitution without circuit modification.

Q: Why is the AD22057R classified as obsolete?

A: The AD22057R has reached end-of-life status with Analog Devices Inc. The AD22057RZ represents the active production equivalent within the same product family, offering continued support and supply availability.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching the following parameters: differential amplifier function, single-supply operation, 200 µA supply current, -40°C to 125°C operating temperature range, voltage input to analog output conversion, and 8-SOIC surface mount package. All these parameters are identical between the AD22057R and AD22057RZ.

Q: Does the AD22057RZ meet current regulatory compliance standards?

A: Yes. The AD22057RZ is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement in most jurisdictions. Compliance status for the AD22057R is not specified.

Q: Are there any differences in packaging between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pin configuration and PCB footprint. The AD22057RZ is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility.

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

A: Both the AD22057R and AD22057RZ have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
