Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX528EWG is determined by strict equivalence across the following critical parameters:

• Resolution & Converter Count: 8-bit resolution with 8 independent D/A converters
• Electrical Performance: Settling time of 3µs, INL/DNL of ±0.3 LSB, R-2R architecture
• Interface & Reference: SPI data interface with external reference capability
• Supply Voltage Ranges: Analog supply 10.8V ~ 16.5V and -1.5V ~ -5.5V; Digital supply 10.8V ~ 16.5V
• Output Characteristics: Buffered voltage output, no differential output
• Package Compatibility: 24-SOIC surface mount package with identical physical dimensions

The MAX528EWG+ meets all these criteria and qualifies as a direct substitute based on identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX528EWG+ is the direct equivalent for the obsolete MAX528EWG. Both parts share identical electrical specifications, performance characteristics, and physical packaging. The primary distinction is product lifecycle status: the MAX528EWG is obsolete, while the MAX528EWG+ is active and available for procurement.

The MAX528EWG+ additionally provides ROHS3 compliance, whereas the original MAX528EWG is RoHS non-compliant. For new designs and production applications, the MAX528EWG+ is the appropriate selection. For legacy system maintenance requiring exact part matching, the MAX528EWG remains functionally equivalent where supply permits.

Frequently Asked Questions (FAQ)

Q: Can MAX528EWG+ be used as a direct replacement for MAX528EWG in existing designs?

A: Yes. The MAX528EWG+ is electrically and mechanically identical to the MAX528EWG. All electrical parameters, pin configurations, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between MAX528EWG and MAX528EWG+?

A: The parts are functionally identical. The primary differences are product status (MAX528EWG is obsolete; MAX528EWG+ is active) and RoHS compliance (MAX528EWG is non-compliant; MAX528EWG+ is ROHS3 compliant).

Q: Are there any package or pinout differences?

A: No. Both parts use the 24-SOIC package with identical physical dimensions (0.295", 7.50mm width) and identical pin assignments.

Q: Which part should be selected for new production?

A: The MAX528EWG+ should be selected for new production due to its active status and ROHS3 compliance.

Q: Is the SPI interface identical between both parts?

A: Yes. Both parts implement the same SPI data interface with identical protocol and timing specifications.

Q: Are the supply voltage requirements the same?

A: Yes. Both parts require identical analog supply voltage (10.8V ~ 16.5V, -1.5V ~ -5.5V) and digital supply voltage (10.8V ~ 16.5V).
