MAX509ACAP Equivalent & Substitute Parts

Part Overview

The MAX509ACAP 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 SPI interface compatibility, external reference capability, and dual supply operation (±5V analog, 5V digital). The MAX509ACAP is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or production continuity planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX509ACAP is determined by strict equivalence across the following critical parameters: 8-bit resolution, 4-channel DAC configuration, SPI digital interface, external reference architecture, buffered voltage output, dual supply requirements (±5V analog, 5V digital), R-2R converter architecture, 6µs typical settling time, ±1 LSB INL/DNL specification, 20-SSOP package geometry, and surface mount capability. The substitute part must maintain identical electrical performance characteristics and physical form factor to ensure direct replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The MAX509ACAP+ is the direct active substitute for the obsolete MAX509ACAP. Both components maintain identical electrical specifications and physical packaging, ensuring pin-for-pin compatibility and functional equivalence. The primary distinction is product status: MAX509ACAP+ is actively manufactured and supported, whereas MAX509ACAP is obsolete. Additionally, MAX509ACAP+ achieves ROHS3 compliance, meeting current environmental and regulatory requirements for new product designs and manufacturing operations. For applications requiring RoHS non-compliant components, MAX509ACAP inventory remains available; however, MAX509ACAP+ is the recommended selection for long-term supply chain stability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can MAX509ACAP+ directly replace MAX509ACAP in existing designs? A: Yes. Both components are electrically and mechanically identical across all specified parameters. Pin configuration, signal timing, supply requirements, and output characteristics are equivalent. No circuit modifications are required.

Q: What is the primary reason to transition from MAX509ACAP to MAX509ACAP+? A: MAX509ACAP is classified as obsolete, creating supply chain risk. MAX509ACAP+ is actively produced and supported by Analog Devices Inc./Maxim Integrated, ensuring long-term availability and manufacturing continuity.

Q: Are there compliance differences between these parts? A: Yes. MAX509ACAP is RoHS non-compliant, while MAX509ACAP+ is ROHS3 compliant. For applications subject to RoHS regulations, MAX509ACAP+ is the required selection.

Q: Does packaging differ between MAX509ACAP and MAX509ACAP+? A: Both components use 20-SSOP surface mount packaging with identical physical dimensions (0.209" width, 5.30mm). MAX509ACAP+ is supplied in tube packaging, while MAX509ACAP packaging is not specified.

Q: Are the electrical performance characteristics identical? A: Yes. Resolution (8-bit), channel count (4), settling time (6µs typical), linearity (±1 LSB INL/DNL), supply voltages (±5V analog, 5V digital), and all other electrical parameters are identical.

Q: What is the operating temperature range for both parts? A: Both MAX509ACAP and MAX509ACAP+ operate across 0°C to 70°C.
