Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX528CWG is determined by strict equivalence across the following critical parameters:

• Resolution & Converter Count: 8-bit resolution with 8 independent D/A converters
• Electrical Performance: 3µs settling time, ±0.3 LSB INL/DNL, R-2R architecture
• Interface & Reference: SPI data interface with external reference capability
• Supply Voltage Compatibility: Dual supply operation (10.8V ~ 16.5V analog and digital, -1.5V ~ -5.5V negative supply)
• Output Configuration: Buffered voltage output, non-differential
• Package Compatibility: 24-SOIC surface mount package with identical pinout and mechanical dimensions

The MAX528CWG+ is a direct functional equivalent meeting all specified electrical and mechanical parameters while maintaining identical pin configuration and package footprint.

Parameter Comparison

Engineering Selection Recommendations

The MAX528CWG+ is the direct substitute for the MAX528CWG. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, pin configuration, and package footprint. The primary distinction is product lifecycle status: the MAX528CWG is obsolete, while the MAX528CWG+ maintains active production status.

For new designs and production continuity, the MAX528CWG+ is the appropriate selection. The MAX528CWG+ additionally provides ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can MAX528CWG+ be used as a direct replacement for MAX528CWG in existing designs?

A: Yes. The MAX528CWG+ is a direct functional and pin-compatible substitute. All electrical parameters, settling time, resolution, supply voltage requirements, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between MAX528CWG and MAX528CWG+?

A: The primary differences are product status and regulatory compliance. The MAX528CWG is obsolete, while MAX528CWG+ is in active production. The MAX528CWG+ meets ROHS3 compliance standards, whereas the MAX528CWG is RoHS non-compliant. Electrical performance and functionality are identical.

Q: Are there any package or pinout differences?
