MX7582K/D Equivalent & Substitute Parts

Part Overview

The MX7582K/D is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, configured as a die package with 4 single-ended inputs and SAR (Successive Approximation Register) architecture. This component is classified as obsolete and has been discontinued from active production. Due to its obsolete status and limited availability in die form, identifying functionally equivalent substitute parts is essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MX7582K/D is determined by the following critical parameters that must remain consistent:

• Resolution: 12-bit conversion capability
• Channel Count: 4 input channels
• Input Configuration: Single-ended inputs
• Architecture: SAR-based analog to digital conversion
• Data Interface: Parallel output
• Supply Voltages: 15V analog and digital supplies
• Sampling Rate: 10 kSPS minimum performance
• Reference Input: External reference requirement

The primary substitute, MX7582KN+, maintains functional equivalence across all critical electrical parameters while transitioning from die packaging to a 28-pin DIP (Dual In-line Package) format. This packaging change enables integration into standard PCB designs and represents the active production equivalent of the obsolete die version.

Parameter Comparison

Engineering Selection Recommendations

The MX7582KN+ is the direct functional equivalent and recommended substitute for the obsolete MX7582K/D. Both components share identical electrical specifications, resolution, channel configuration, and supply requirements. The transition from die to 28-pin DIP packaging eliminates the need for specialized die-attach and wire-bonding processes, reducing assembly complexity and cost.

The MX7582KN+ maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability and technical support. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The substitute part is available in higher inventory quantities (1600 units) compared to the obsolete die version, providing supply chain stability for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the MX7582KN+ directly replace the MX7582K/D in existing designs?

A: The MX7582KN+ provides electrical and functional equivalence. The primary design consideration is the packaging transition from die to 28-pin DIP format. Existing die-based implementations require PCB redesign to accommodate the DIP package footprint and pin configuration.

Q: Are the pin assignments identical between the die and DIP versions?

A: Both versions maintain the same functional pin assignments for the 4 input channels, parallel data output, supply pins, and external reference input. The DIP package provides these connections through standard through-hole or surface-mount pin headers.

Q: What are the compliance and regulatory differences between these parts?

A: Both the MX7582K/D and MX7582KN+ are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels are identical at MSL 1 (Unlimited). No regulatory or compliance barriers exist for substitution.

Q: Why is the MX7582K/D classified as obsolete?

A: The die format has been superseded by the packaged DIP version (MX7582KN+), which offers improved manufacturability, integration flexibility, and supply chain accessibility. Analog Devices Inc./Maxim Integrated has transitioned production focus to the active DIP package variant.

Q: Are there inventory considerations for the substitute part?

A: The MX7582KN+ is actively manufactured and maintained in inventory (1600 units available). The obsolete MX7582K/D die version has limited remaining stock (906 units). For new designs and ongoing production, the substitute part provides superior supply chain reliability.
