Substitute Part Grouping Explanation

Substitution of the MAX5258EEE is determined by strict equivalence across the following critical parameters:

• Resolution & Converter Count: 8-bit resolution with 8 independent D/A converters
• Interface Protocol: SPI digital interface for command and data transmission
• Output Characteristics: Buffered voltage output with external reference input
• Supply Voltage Requirements: Dual 5V supplies (analog and digital)
• Accuracy Specifications: INL/DNL performance of ±0.1 LSB and ±0.05 LSB respectively
• Thermal Performance: 10µs typical settling time and -40°C to 85°C operating range
• Physical Form Factor: 16-SSOP surface mount package with 0.154" width

The MAX5258EEE+ qualifies as a direct substitute based on identical electrical specifications and package compatibility. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX5258EEE+ is the direct functional equivalent of the MAX5258EEE with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

For New Designs and Long-Term Support: The MAX5258EEE+ is the appropriate choice due to active product status and ROHS3 compliance certification. This ensures continued manufacturer support, availability, and regulatory alignment with current environmental standards.

For Legacy System Maintenance: The MAX5258EEE remains functionally equivalent for applications where existing inventory is available and RoHS compliance is not a design requirement. However, the obsolete status indicates limited future availability.

Packaging Consideration: Both parts are supplied in 16-QSOP packaging. The MAX5258EEE+ is available in tube packaging, while the MAX5258EEE packaging specification is not detailed. Verify packaging requirements for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX5258EEE+ directly replace the MAX5258EEE in existing designs?

A: Yes. The MAX5258EEE+ provides identical electrical performance, settling time, accuracy specifications, and package form factor. No circuit modifications are required for direct substitution.

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

A: The MAX5258EEE is classified as obsolete, indicating discontinued manufacturing and limited availability. The MAX5258EEE+ is active, ensuring ongoing production and manufacturer support.

Q: Does RoHS compliance affect functional compatibility?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical function. Both parts operate identically in circuit applications. RoHS3 compliance of the MAX5258EEE+ aligns with current regulatory requirements for new designs and procurement.

Q: Are there any differences in supply voltage requirements?

A: No. Both parts require identical 5V analog and digital supply voltages with the same accuracy specifications (INL/DNL ±0.1, ±0.05 LSB).

Q: What is the significance of the packaging designation change from 16-QSOP to 16-SSOP?

A: The 16-SSOP (0.154", 3.90mm Width) is the standard package form factor for both parts. This is a surface mount package suitable for automated assembly. Verify PCB footprint compatibility with your design.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain identical operating temperature range specifications of -40°C to 85°C and equivalent settling time performance across this range.
