MAX5123BEEE+ Equivalent & Substitute Parts

Part Overview

The MAX5123BEEE+ is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring single-channel voltage output conversion. This component operates with external or internal reference sources and is housed in a 16-QSOP surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the MAX5123BEEE+ is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Output Configuration: Single-channel voltage output with buffered architecture
• Interface Protocol: SPI digital communication
• Reference Options: Support for both external and internal reference sources
• Supply Voltage Range: 2.7V to 3.6V for both analog and digital supplies
• Settling Time: 20µs typical response time
• Linearity Specifications: INL/DNL performance of ±2 LSB (Max) and ±1 LSB (Max)
• Package Compatibility: 16-QSOP surface mount package with 0.154" width (3.90mm)
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The MAX5121BEEE+ meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package dimensions, and compliance certifications, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations
