Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX5174AEEE is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Channel Configuration: Single DAC channel
• Output Architecture: Buffered voltage output with R-2R topology
• Interface Protocol: SPI serial communication
• Reference Configuration: External reference input
• Supply Voltage Requirements: 5V analog and digital supplies
• Settling Performance: 18µs typical settling time
• Accuracy Specifications: ±1 LSB maximum INL/DNL
• Temperature Operating Range: -40°C to 85°C
• Physical Package: 16-SSOP surface mount form factor

The substitute part MAX5174AEEE+ maintains identical electrical specifications and mechanical compatibility with the original part number, differing only in compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

The MAX5174AEEE+ serves as a direct functional equivalent to the MAX5174AEEE, providing identical electrical performance and mechanical compatibility. The primary distinction between these part numbers is regulatory compliance status: MAX5174AEEE+ achieves ROHS3 compliance, whereas the original MAX5174AEEE does not. Both parts maintain REACH unaffected status and identical ECCN/HTSUS classifications.

For applications requiring RoHS compliance or subject to environmental regulations mandating lead-free component usage, MAX5174AEEE+ is the appropriate selection. For legacy systems or applications without compliance requirements, either part number provides equivalent functional performance.
