Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX7548JCWP is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Output Configuration: Current output, unbuffered topology
• Data Interface: Parallel input structure
• Reference Architecture: External reference requirement
• Conversion Architecture: R-2R resistor network
• Package Specification: 20-SOIC form factor with identical pin configuration
• Supply Voltage Compatibility: Dual supply operation at 5V and 11.4V to 15.75V
• Electrical Performance: INL/DNL specification of ±1 LSB maximum
• Thermal Operating Range: 0°C to 70°C

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original MX7548JCWP, ensuring direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

MX7548JCWP+ (Direct Successor)

The MX7548JCWP+ is the direct active replacement for the obsolete MX7548JCWP. Both parts share identical electrical specifications and 20-SOIC packaging. The primary distinction is product status: MX7548JCWP+ is active and ROHS3 compliant, whereas the original is obsolete and RoHS non-compliant. Selection of MX7548JCWP+ ensures regulatory compliance and ongoing supply chain support.

AD7548JRZ Series (Manufacturer-Recommended Alternatives)

The AD7548JRZ, AD7548JRZ-REEL, and AD7548JRZ-REEL7 are manufacturer-recommended alternatives from Analog Devices Inc. All three variants maintain identical electrical performance and 20-SOIC packaging. The AD7548JRZ series exhibits a typical settling time of 1.5µs compared to the 1µs specification of the MX7548JCWP, which remains within acceptable tolerance for most applications. All AD7548 variants are active products with ROHS3 compliance.

Packaging Considerations

• MX7548JCWP+: Tube packaging for standard component handling
• AD7548JRZ: Tube packaging for standard component handling
• AD7548JRZ-REEL: Tape & Reel packaging for automated assembly
• AD7548JRZ-REEL7: Tape & Reel packaging (7-inch reel) for high-volume automated assembly

Selection between tube and tape & reel packaging depends on assembly process requirements and order quantities.

Frequently Asked Questions (FAQ)

Q: Can the AD7548JRZ series directly replace the MX7548JCWP in existing designs?

A: Yes. The AD7548JRZ, AD7548JRZ-REEL, and AD7548JRZ-REEL7 are functionally equivalent to the MX7548JCWP. All parts share identical pin configuration, electrical specifications, and 20-SOIC package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between the settling time specifications of MX7548JCWP (1µs) and AD7548JRZ (1.5µs typical)?

A: The MX7548JCWP specifies a maximum settling time of 1µs, while the AD7548JRZ specifies a typical settling time of 1.5µs. Both specifications fall within acceptable performance ranges for 12-bit DAC applications. Applications with strict settling time requirements should verify compatibility with the AD7548JRZ specification before substitution.

Q: What is the difference between MX7548JCWP+ and the AD7548JRZ variants?

A: MX7548JCWP+ is a Maxim Integrated product, while AD7548JRZ variants are Analog Devices products. Both manufacturers are part of the same organization. Electrical specifications and package dimensions are identical. The primary differences are product status (both active), packaging format (tube vs. tape & reel), and supply chain availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MX7548JCWP+, AD7548JRZ, AD7548JRZ-REEL, and AD7548JRZ-REEL7 are all ROHS3 compliant. The original MX7548JCWP is RoHS non-compliant. Substitution with any of the listed alternatives ensures regulatory compliance for new designs and manufacturing processes.

Q: Which substitute part should be selected for high-volume automated assembly?

A: AD7548JRZ-REEL or AD7548JRZ-REEL7 are recommended for automated assembly processes. Both are supplied in tape & reel packaging. AD7548JRZ-REEL7 (7-inch reel) is suitable for high-volume production runs. Standard tube packaging (MX7548JCWP+, AD7548JRZ) is appropriate for lower-volume or manual assembly applications.

Q: Are the supply voltage requirements identical across all substitute parts?

A: Yes. All substitute parts operate with identical dual supply voltage specifications: 5V and 11.4V to 15.75V for both analog and digital supplies. No power supply modifications are required when substituting between any of the listed parts.

Q: What is the operating temperature range for all substitute parts?

A: All parts, including the original MX7548JCWP and all substitutes, operate across the 0°C to 70°C temperature range. No thermal performance differences exist between the original and substitute parts.
