Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX528CPP 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: 20-DIP through-hole package (0.300", 7.62mm)
• Operating Temperature: 0°C ~ 70°C range

Only parts meeting all these parameters are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX528CPP+ serves as the direct functional equivalent to the MAX528CPP with identical electrical and mechanical specifications. The primary distinction lies in product status and regulatory compliance. The MAX528CPP is obsolete, whereas the MAX528CPP+ maintains active production status, ensuring long-term availability and supply chain continuity.

The MAX528CPP+ achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions, whereas the original MAX528CPP is non-compliant. For new designs or systems requiring regulatory adherence to modern standards, the MAX528CPP+ is the appropriate selection. Both parts maintain identical performance characteristics across resolution, settling time, linearity, supply voltage ranges, and package configuration, ensuring direct functional interchangeability in circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can MAX528CPP+ replace MAX528CPP in existing designs?

A: Yes. The MAX528CPP+ is electrically and mechanically identical to the MAX528CPP. All functional parameters, including 8-bit resolution, 3µs settling time, SPI interface, supply voltage ranges, and 20-DIP package configuration, are equivalent. Direct substitution is possible without circuit modification.

Q: What is the primary reason to transition from MAX528CPP to MAX528CPP+?

A: The MAX528CPP is classified as obsolete, creating supply and support risks. The MAX528CPP+ maintains active production status and achieves ROHS3 compliance, providing regulatory alignment and assured availability for current and future applications.

Q: Are there packaging differences between these parts?

A: The MAX528CPP+ is supplied in tube packaging, whereas the original MAX528CPP packaging specification is not detailed. Both parts use identical 20-DIP through-hole package geometry (0.300", 7.62mm), ensuring mechanical compatibility on printed circuit boards.

Q: Do these parts require different circuit design considerations?

A: No. Both parts operate with identical supply voltage ranges (analog: 10.8V ~ 16.5V, -1.5V ~ -5.5V; digital: 10.8V ~ 16.5V), settling time (3µs), and external reference requirements. Circuit designs are fully compatible without modification.

Q: What compliance certifications apply to each part?

A: The MAX528CPP is RoHS non-compliant and REACH unaffected. The MAX528CPP+ is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8542.39.0001.
