Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5250AEAP is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 10-bit resolution with 4 independent DAC channels
• Interface Protocol: SPI digital interface for control and data input
• Output Configuration: Buffered voltage output with external reference input
• Supply Voltage Requirements: 5V analog and digital supply voltages
• Accuracy Specifications: INL/DNL performance of ±0.25 and ±1 LSB maximum
• Settling Time: 10µs typical response time
• Package Compatibility: 20-SSOP surface mount package with identical pinout and mechanical dimensions

The MAX5250AEAP+ qualifies as a direct substitute based on identical electrical specifications and package form factor. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX5250AEAP+ is the direct functional equivalent of the MAX5250AEAP. Selection between these parts is determined by regulatory and compliance requirements rather than electrical performance.

For applications requiring RoHS3 compliance, the MAX5250AEAP+ is the appropriate selection. This variant maintains identical electrical specifications and package compatibility while meeting current environmental and material restriction directives.

For legacy systems currently utilizing the MAX5250AEAP, the MAX5250AEAP+ provides pin-for-pin and functionally equivalent replacement without circuit modification. The active product status of the MAX5250AEAP+ ensures continued availability and manufacturing support.
