MAX5154BEEE Equivalent & Substitute Parts
Part Overview
The MAX5154BEEE is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring dual voltage-buffered outputs. This component features an R-2R architecture with SPI interface and operates across the industrial temperature range of -40°C to 85°C.
The MAX5154BEEE is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this DAC architecture.

Substitute Part Grouping Explanation
Substitution for the MAX5154BEEE is determined by strict equivalence across the following critical parameters:
- 12-bit resolution with dual D/A converters
- Voltage-buffered output configuration
- SPI serial data interface
- External reference input requirement
- 15µs typical settling time
- 5V analog and digital supply voltages
- ±1 LSB maximum INL and DNL specifications
- R-2R resistor ladder architecture
- 16-SSOP surface mount package
- Industrial temperature range (-40°C to 85°C)
The substitute parts identified—MAX5154BEEE+ and MAX5156BEEE+—maintain full electrical and mechanical compatibility with the original MAX5154BEEE across all specified parameters. These parts are functionally interchangeable within the defined operating conditions.

Engineering Selection Recommendations
The MAX5154BEEE+ is the direct functional equivalent with identical electrical specifications and package configuration. This part is currently in active production status and carries ROHS3 compliance certification, making it the primary substitute for new designs or production continuity.
The MAX5156BEEE+ is a parametric equivalent offering the same electrical performance and package footprint. This part is also in active production with ROHS3 compliance and represents an alternative source for supply chain diversification.
Both substitute parts maintain full compatibility with existing PCB layouts and firmware implementations designed for the MAX5154BEEE. The transition from the obsolete MAX5154BEEE to either active substitute requires no circuit modifications or design changes.
Frequently Asked Questions (FAQ)
Q: Can MAX5154BEEE+ be used as a direct replacement for MAX5154BEEE?
A: Yes. The MAX5154BEEE+ maintains identical electrical specifications, settling time, output characteristics, and 16-SSOP package configuration. No circuit modifications are required.
Q: What is the difference between MAX5154BEEE+ and MAX5156BEEE+?
A: Both parts are parametric equivalents with identical 12-bit resolution, dual DAC configuration, SPI interface, and performance specifications. The primary difference is the base product number designation (MAX5154 versus MAX5156). Both are functionally interchangeable within the specified electrical and mechanical parameters.
Q: Are there compliance differences between the original and substitute parts?
A: Yes. The MAX5154BEEE is RoHS non-compliant, while both MAX5154BEEE+ and MAX5156BEEE+ are ROHS3 compliant. Both substitute parts maintain REACH Unaffected status and EAR99 export classification identical to the original.
Q: Does the 16-QSOP packaging differ between parts?
A: No. All three parts use the 16-SSOP package with 0.154" width (3.90mm). The package footprint, pin configuration, and mounting requirements are identical.
Q: What is the inventory status for substitute parts?
A: MAX5154BEEE+ has 1900 pieces in stock. MAX5156BEEE+ has 1042 pieces in stock. Both are available as new original components in active production.
