Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD7245JPZ is determined by the following critical parameters:

• Resolution: 12-bit conversion capability
• Output Configuration: Buffered voltage output with internal reference
• Data Interface: Parallel input structure
• Package Compatibility: 28-PLCC (11.51x11.51) surface mount form factor
• Electrical Specifications: INL/DNL performance of ±1 LSB maximum
• Operating Temperature Range: 0°C to 70°C
• Compliance: ROHS3 and REACH compliance status

The MX7245JP+ meets these core substitution criteria while maintaining functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the AD7245JPZ and MX7245JP+ are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The MX7245JP+ demonstrates broader analog and digital supply voltage tolerance, accepting lower minimum supply voltages (11.4V versus 14.25V). This characteristic may provide operational flexibility in applications with variable power supply conditions, provided the design operates within the overlapping voltage range of ±14.25V to 15.75V for analog supply and 14.25V to 15.75V for digital supply. Both components share identical resolution, output buffering, settling time performance at 5µs, and package form factor, ensuring direct functional substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can MX7245JP+ directly replace AD7245JPZ in existing designs?

A: Yes, for applications operating within the overlapping supply voltage range (±14.25V to 15.75V analog, 14.25V to 15.75V digital). Both components share identical 12-bit resolution, buffered voltage output, parallel interface, internal reference architecture, and 28-PLCC package specifications.

Q: What is the key difference between these two parts?

A: The primary difference is supply voltage tolerance. The MX7245JP+ accepts lower minimum supply voltages (11.4V minimum) compared to the AD7245JPZ (14.25V minimum), while maintaining the same upper voltage limits. Both parts deliver identical electrical performance within their overlapping operating ranges.

Q: Are there any settling time differences?

A: The AD7245JPZ specifies settling time options of 5µs or 10µs, while the MX7245JP+ specifies 5µs. For applications requiring 5µs settling time, both parts are equivalent. Applications requiring 10µs settling time should verify that the MX7245JP+ 5µs specification meets performance requirements.

Q: Do both parts have the same moisture sensitivity rating?

A: No. The AD7245JPZ has MSL 3 (168 hours), while the MX7245JP+ has MSL 1 (Unlimited). The MX7245JP+ demonstrates superior moisture resistance, which may provide advantages in high-humidity storage or assembly environments.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the AD7245JPZ and MX7245JP+ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
