MAX500ACPE Equivalent & Substitute Parts

Part Overview

The MAX500ACPE is an 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring four independent voltage output channels. This component features an R-2R architecture with external reference capability and I2C data interface, operating across dual supply voltages of 11.4V to 16.5V for both analog and digital domains.

The MAX500ACPE is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this component is specified in active applications or inventory management requires active alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX500ACPE is determined by strict equivalence across the following critical parameters:

• Resolution & Channel Count: 8-bit resolution with 4 independent D/A converters
• Output Configuration: Voltage-buffered output with external reference
• Interface Protocol: I2C data interface
• Electrical Performance: Settling time of 4.5µs, INL/DNL specifications of ±0.5 LSB (Max) and ±1 LSB (Max)
• Supply Voltage Range: Dual supply operation at 11.4V ~ 16.5V for both analog and digital domains
• Package Compatibility: 16-DIP through-hole package (0.300", 7.62mm)
• Architecture: R-2R resistor network topology

The MAX500ACPE+ qualifies as a direct substitute based on identical electrical specifications, functional performance, and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MAX500ACPE+ is the direct functional equivalent of the MAX500ACPE, with identical electrical performance and mechanical compatibility. The primary distinction is product lifecycle status: the MAX500ACPE is obsolete, while the MAX500ACPE+ maintains active production status.

For new designs or system refreshes, the MAX500ACPE+ is the appropriate selection. The MAX500ACPE+ additionally provides ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original MAX500ACPE is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

For legacy system maintenance where the MAX500ACPE is currently specified, the MAX500ACPE+ provides drop-in compatibility without circuit redesign, provided that RoHS compliance requirements are satisfied by the system design.

Frequently Asked Questions (FAQ)

Q: Can the MAX500ACPE+ directly replace the MAX500ACPE in existing circuits?

A: Yes. The MAX500ACPE+ is electrically and mechanically identical to the MAX500ACPE. Both components feature the same 8-bit resolution, 4-channel configuration, I2C interface, settling time, supply voltage range, and 16-DIP through-hole package. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from MAX500ACPE to MAX500ACPE+?

A: The MAX500ACPE is classified as obsolete product status, creating supply chain risk. The MAX500ACPE+ is in active production, ensuring long-term availability. Additionally, the MAX500ACPE+ is ROHS3 compliant, meeting current environmental regulations, whereas the MAX500ACPE is RoHS non-compliant.

Q: Are there any differences in packaging between these parts?

A: Both parts use the 16-DIP (0.300", 7.62mm) through-hole package. The MAX500ACPE+ is supplied in tube packaging, while the original MAX500ACPE packaging specification is not detailed. This difference does not affect electrical or mechanical compatibility.

Q: Do both parts require the same external reference circuit?

A: Yes. Both the MAX500ACPE and MAX500ACPE+ use external reference type configuration. The external reference circuit design remains identical between the two parts.

Q: What is the operating temperature range for both parts?

A: Both the MAX500ACPE and MAX500ACPE+ operate across 0°C to 70°C. Temperature performance is identical between the two components.
