Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD9225AR is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling Rate: 12-bit resolution at 25 MSPS
• Input Configuration: Single input supporting both differential and single-ended modes
• Architecture: Pipelined ADC topology
• Data Interface: Parallel output
• Reference Flexibility: Support for both external and internal voltage references
• Supply Voltage Compatibility: Analog supply at 5V; digital supply range 2.85V ~ 5.25V
• Package and Pinout: 28-SOIC form factor with identical mechanical and electrical pinout
• Temperature Range: -40°C to 85°C operation

The AD9225ARZ qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AD9225ARZ is the direct substitute for the AD9225AR. Both devices share identical electrical specifications, pinout, and package configuration. The primary distinction is product status: the AD9225AR is obsolete, while the AD9225ARZ maintains active production status.

For new designs or system maintenance requiring the AD9225AR functionality, the AD9225ARZ is the appropriate selection. The AD9225ARZ carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the AD9225ARZ directly replace the AD9225AR in existing designs?

A: Yes. The AD9225ARZ is electrically and mechanically identical to the AD9225AR. No circuit modifications, PCB layout changes, or firmware adjustments are required for substitution.

Q: What is the difference between AD9225AR and AD9225ARZ?

A: The devices are functionally equivalent. The primary difference is packaging: AD9225AR uses standard packaging, while AD9225ARZ is supplied in tube packaging. Additionally, AD9225ARZ maintains active product status with current manufacturing support, whereas AD9225AR is obsolete.

Q: Are there any compliance differences between these parts?

A: The AD9225ARZ includes RoHS3 compliance and REACH unaffected status documentation. The AD9225AR, as an obsolete part, may not have current compliance certifications. For applications requiring regulatory compliance documentation, the AD9225ARZ is the recommended choice.

Q: Can I use the AD9225ARZ in applications originally designed for the AD9225AR?

A: Yes. Complete parameter equivalence across resolution, sampling rate, input configuration, supply voltages, temperature range, and package ensures full compatibility in all applications where the AD9225AR was originally specified.

Q: What is the MSL rating for these devices?

A: Both the AD9225AR and AD9225ARZ carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
