MAX509BEAP Equivalent & Substitute Parts

Part Overview

The MAX509BEAP is an 8-bit digital-to-analog converter (DAC) with four independent output channels, manufactured by Analog Devices Inc./Maxim Integrated. This component features voltage-buffered outputs, SPI data interface, and external reference capability, operating from ±5V analog and 5V digital supply rails. The MAX509BEAP is classified as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Active alternatives with identical electrical and mechanical specifications are available to support ongoing production and maintenance requirements.

Substitute Part Grouping Explanation

Substitution of the MAX509BEAP is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts identified maintain identical specifications in the following critical areas:

• Resolution: 8-bit conversion
• Channel count: 4 independent D/A converters
• Output configuration: Voltage-buffered topology
• Interface protocol: SPI serial communication
• Supply requirements: ±5V analog, 5V digital
• Accuracy: ±1 LSB maximum INL/DNL
• Conversion architecture: R-2R resistor ladder
• Thermal operating range: -40°C to 85°C
• Physical form factor: 20-SSOP surface mount package

All substitute parts share the MAX509 base product number and are manufactured by Analog Devices Inc./Maxim Integrated, ensuring design and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MAX509BEAP is obsolete and no longer in active production. Both MAX509AEAP+ and MAX509BEAP+ are active alternatives that maintain complete electrical and mechanical equivalence to the original part.

For new designs and ongoing production, MAX509AEAP+ or MAX509BEAP+ are the appropriate selections. Both substitute parts are ROHS3 compliant, addressing regulatory requirements that the original MAX509BEAP does not meet. The active product status of these alternatives ensures long-term availability and supply chain stability.

Selection between MAX509AEAP+ and MAX509BEAP+ is determined by packaging requirements. MAX509AEAP+ is supplied in tube packaging, while MAX509BEAP+ is also supplied in tube packaging. Both parts are functionally and electrically identical and are interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can MAX509AEAP+ and MAX509BEAP+ be used interchangeably with MAX509BEAP?

A: Yes. All three parts share identical electrical specifications, pin configurations, and mechanical form factors. The 20-SSOP surface mount package is consistent across all variants, and the SPI interface, supply requirements, and output characteristics are equivalent.

Q: What is the primary difference between the substitute parts and the original MAX509BEAP?

A: The primary differences are product status and regulatory compliance. MAX509AEAP+ and MAX509BEAP+ are active products with ROHS3 compliance, while MAX509BEAP is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between MAX509AEAP+ and MAX509BEAP+?

A: Both parts are supplied in tube packaging. No packaging differentiation exists between these two alternatives.

Q: Does the 20-SSOP package remain consistent across all three part numbers?

A: Yes. All three parts use the 20-SSOP package with 0.209" width and 5.30mm dimensions. PCB footprints and assembly processes are identical.

Q: What supply voltages are required for operation?

A: The MAX509BEAP, MAX509AEAP+, and MAX509BEAP+ all require ±5V for analog supply and 5V for digital supply. External reference voltage is required for DAC operation.

Q: Is the SPI interface identical across all variants?

A: Yes. All three parts implement the same SPI serial communication protocol with identical timing and control characteristics.
