Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX528EAG is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 8-bit resolution with 8 independent D/A converters
• Electrical Performance: 3µs settling time, ±0.3 LSB INL/DNL, R-2R architecture
• Interface and Reference: SPI data interface with external reference configuration
• Supply Voltage Compatibility: Dual supply operation (analog and digital) within specified ranges
• Output Characteristics: Buffered voltage output, no differential output requirement
• Package Compatibility: 24-SSOP surface mount package with identical physical dimensions

The MAX528EAG+ qualifies as a direct substitute, maintaining all electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX528EAG+ is the direct substitute for the MAX528EAG. Both components share identical electrical specifications, pin configurations, and functional characteristics. The primary distinction lies in product status and regulatory compliance:

• MAX528EAG: Obsolete status with RoHS non-compliant certification
• MAX528EAG+: Active product status with ROHS3 compliance

For new designs and ongoing system support, the MAX528EAG+ is the appropriate selection. This part maintains full electrical and mechanical compatibility while providing active manufacturer support and compliance with current environmental regulations. The MAX528EAG+ is available in tube packaging, suitable for production environments.

Frequently Asked Questions (FAQ)

Q: Can MAX528EAG+ be used as a direct replacement for MAX528EAG in existing designs?

A: Yes. The MAX528EAG+ is electrically and mechanically identical to the MAX528EAG. All electrical parameters, pin assignments, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between MAX528EAG and MAX528EAG+?

A: The primary differences are product status and compliance certifications. The MAX528EAG is obsolete and RoHS non-compliant, while the MAX528EAG+ is an active product with ROHS3 compliance. Electrical performance and functionality are identical.

Q: Are there any package differences between these parts?
