Substitute Part Grouping Explanation

Substitution of the AD9220ARS is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the AD9220ARSZ, which maintains identical specifications for resolution, sampling rate, input configuration, architecture, voltage requirements, temperature range, and package form factor. The substitution is valid because both parts share the same base product number (AD9220) and implement identical functional specifications.

The key parameters governing substitution are:

• 12-bit resolution
• 10 MHz sampling rate
• Single input channel
• Pipelined architecture
• Parallel data interface
• 28-SSOP surface mount package
• Identical supply voltage requirements

Parameter Comparison

Engineering Selection Recommendations

The AD9220ARSZ is the direct equivalent for the obsolete AD9220ARS. Both parts are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications. The AD9220ARSZ is currently in active production status, making it the appropriate selection for new designs and system replacements.

The AD9220ARSZ provides additional compliance documentation: ROHS3 compliance and REACH unaffected status. These certifications support regulatory requirements in applications subject to environmental and hazardous substance restrictions.

Packaging differs only in delivery format: the AD9220ARS is supplied as loose components, while the AD9220ARSZ is supplied in tube packaging. This distinction does not affect electrical performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can AD9220ARSZ directly replace AD9220ARS in existing designs? A: Yes. Both parts implement identical electrical specifications, pin configurations, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between AD9220ARS and AD9220ARSZ? A: The parts are electrically and mechanically identical. The primary differences are product status (obsolete vs. active) and packaging format (loose vs. tube). The AD9220ARSZ includes ROHS3 and REACH compliance documentation.

Q: Are there any pin compatibility concerns? A: No. Both parts use the 28-SSOP package with identical pinout and electrical characteristics.

Q: What supply voltages are required? A: Analog supply requires 5V. Digital supply operates across 2.7V to 5.25V range.

Q: Is the 28-SSOP package suitable for automated assembly? A: Yes. Both parts are surface mount devices compatible with standard pick-and-place and reflow soldering processes.

Q: What is the moisture sensitivity rating? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
