Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX7534J/D is determined by the following core parameters:

• 14-bit resolution with single D/A converter configuration
• 1.5µs settling time performance
• Unbuffered current output topology
• Parallel data interface with external reference
• R-2R resistor ladder architecture
• Dual supply voltage range: 11.4V ~ 15.75V (analog and digital)
• Operating temperature range: 0°C ~ 70°C
• INL/DNL specifications within ±2 LSB and ±1 LSB respectively

The MX7534KN+ qualifies as a direct functional substitute, maintaining identical electrical specifications while differing in package configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

The MX7534KN+ serves as the primary substitute for the obsolete MX7534J/D. Both components share identical core electrical specifications and R-2R architecture, ensuring functional compatibility in parallel data interface applications requiring 14-bit resolution and external reference configuration.

The MX7534KN+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, this substitute achieves ROHS3 compliance, meeting modern environmental and regulatory requirements that the original MX7534J/D does not satisfy.

The primary design consideration involves package transition: the MX7534J/D die package requires specialized handling and integration, while the MX7534KN+ 20-DIP through-hole package accommodates standard PCB assembly processes. This packaging difference necessitates circuit board redesign but provides superior long-term supply chain stability.

INL/DNL performance of the MX7534KN+ (±1 LSB maximum for both parameters) exceeds the original specification (±2 LSB INL), providing improved linearity characteristics.

Frequently Asked Questions (FAQ)

Q: Can the MX7534KN+ directly replace the MX7534J/D without circuit modifications?

A: Electrical substitution is valid; however, the package transition from die to 20-DIP requires PCB redesign. The MX7534KN+ through-hole configuration is incompatible with surface-mount die footprints.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitutes must maintain 14-bit resolution, 1.5µs settling time, unbuffered current output, parallel data interface, external reference configuration, R-2R architecture, and dual supply voltage range of 11.4V ~ 15.75V.

Q: Does the MX7534KN+ meet current regulatory compliance standards?

A: Yes. The MX7534KN+ is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The original MX7534J/D is RoHS non-compliant.

Q: Are there performance differences between the MX7534J/D and MX7534KN+?

A: Both components share identical settling time and operating temperature specifications. The MX7534KN+ provides superior INL/DNL performance (±1 LSB maximum versus ±2 LSB INL on the original).

Q: What is the availability status of the MX7534KN+?

A: The MX7534KN+ maintains active product status with established supply channels, contrasting with the obsolete MX7534J/D classification.
