Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADS5542IPAPRG4 is determined by strict equivalence across the following critical parameters:

• 14-bit resolution
• 80 MSPS sampling rate
• Single differential input configuration
• Pipelined architecture
• Parallel data interface
• Internal reference
• 3V to 3.6V dual supply operation
• 64-pin PowerTQFP package footprint
• Surface mount technology

The ADS5542IPAP qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: the main part uses tube packaging, while the substitute uses tray packaging. Both parts share the same base product number (ADS5542) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The ADS5542IPAP is the direct substitute for the ADS5542IPAPRG4. Both parts maintain identical electrical and mechanical specifications, ensuring functional compatibility in existing designs. The ADS5542IPAP carries active product status, providing superior long-term availability compared to the obsolete ADS5542IPAPRG4.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 3 (168 hours) applies uniformly across both variants, requiring standard moisture control during storage and handling.

Selection between these parts should be based on supply chain availability and packaging requirements. The tray packaging of the ADS5542IPAP is suitable for automated assembly processes, while the tube packaging of the ADS5542IPAPRG4 may be preferred for lower-volume manual assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the ADS5542IPAP directly replace the ADS5542IPAPRG4 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The ADS5542IPAP operates at the same 14-bit resolution, 80 MSPS sampling rate, and supply voltage specifications. The 64-pin PowerTQFP package footprint is identical, enabling direct PCB compatibility without design modification.

Q: What is the difference between the ADS5542IPAPRG4 and ADS5542IPAP?

A: The primary difference is packaging format. The ADS5542IPAPRG4 uses tube packaging, while the ADS5542IPAP uses tray packaging. All electrical specifications, pin configurations, and performance characteristics are identical.

Q: Why is the ADS5542IPAPRG4 classified as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active production and support for this specific part variant. The ADS5542IPAP remains in active production, providing continued availability and manufacturer support.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 3 (168 hours). Regulatory and environmental compliance requirements are equivalent.

Q: What packaging considerations apply when switching from ADS5542IPAPRG4 to ADS5542IPAP?

A: Tray packaging (ADS5542IPAP) is optimized for automated pick-and-place assembly and high-volume production. Tube packaging (ADS5542IPAPRG4) is suitable for manual assembly and lower-volume applications. Both formats contain the same component quantity and quality standards.
