Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX552AEUB is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Channel Count: Single D/A converter
• Output Configuration: Current-mode, unbuffered output
• Interface Protocol: SPI serial communication
• Reference Architecture: External reference requirement
• Supply Voltage Ranges: 2.7V to 3.6V for both analog and digital supplies
• Accuracy Specifications: INL/DNL ±0.5 LSB maximum
• Settling Performance: 1µs settling time
• Package Compatibility: 10-TFSOP or 10-MSOP footprint (0.118" width, 3.00mm)
• Temperature Range: -40°C to 85°C operation

Parts meeting all these parameters are classified as direct substitutes. Variations in product status, compliance certifications, or packaging format do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX552AEUB+ is a direct functional equivalent to the MAX552AEUB. Both parts share identical electrical specifications, performance characteristics, and physical packaging. The primary distinctions are product lifecycle status and regulatory compliance.

The MAX552AEUB is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX552AEUB+ maintains active production status, ensuring reliable supply chain access and long-term component availability.

From a compliance perspective, the MAX552AEUB+ achieves ROHS3 compliance, whereas the original MAX552AEUB is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the MAX552AEUB+ is the appropriate selection. Both parts maintain REACH unaffected status and EAR99 export classification.

Selection between these parts should prioritize the MAX552AEUB+ for new designs, system upgrades, or applications requiring regulatory compliance. The MAX552AEUB remains functionally suitable for legacy systems where supply availability and compliance requirements do not present constraints.

Frequently Asked Questions (FAQ)

Q: Can MAX552AEUB+ directly replace MAX552AEUB in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters. The MAX552AEUB+ operates with the same supply voltages, settling time, resolution, and SPI interface protocol. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The MAX552AEUB is obsolete, meaning Analog Devices has discontinued production. The MAX552AEUB+ is active production, ensuring ongoing availability. For applications requiring long-term component supply, the MAX552AEUB+ is the preferred choice.

Q: Does RoHS compliance affect functional performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both parts deliver identical 12-bit DAC functionality. The MAX552AEUB+ is ROHS3 compliant, making it suitable for applications subject to RoHS directives.

Q: Are the package dimensions identical?

A: Yes. Both parts use 10-TFSOP or 10-MSOP packaging with 0.118" width and 3.00mm height. PCB footprints and mounting procedures are identical. The MAX552AEUB+ is supplied in tube packaging format.

Q: What are the critical parameters for substitution?

A: Substitution requires equivalence in 12-bit resolution, single-channel configuration, current-mode unbuffered output, SPI interface, external reference requirement, 2.7V to 3.6V supply range, ±0.5 LSB accuracy, 1µs settling time, and 10-TFSOP/10-MSOP package compatibility.
