Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS8342IPFBT is determined by strict equivalence across the following critical parameters:

• Resolution: 16-bit conversion capability
• Sampling Rate: 250 kSPS minimum performance
• Channel Count: 4 independent input channels
• Input Configuration: Support for Pseudo-Differential and Single Ended inputs
• Data Interface: Parallel output protocol
• Architecture: SAR-based conversion topology
• Reference Input: External reference requirement
• Supply Voltages: ±5V for both analog and digital domains
• Package: 48-TQFP (7x7) form factor
• Operating Temperature: -40°C to +85°C range
• Compliance: ROHS3 and REACH compliance status

The ADS8342IBPFBT qualifies as a direct substitute based on identical electrical specifications and package configuration, with the primary distinction being product lifecycle status and packaging format availability.

Parameter Comparison

Engineering Selection Recommendations

The ADS8342IBPFBT is the direct functional equivalent for the obsolete ADS8342IPFBT. Both devices maintain identical electrical performance specifications, package geometry, and compliance certifications. The primary distinction is product lifecycle status: the ADS8342IPFBT is classified as Obsolete, while the ADS8342IBPFBT carries Last Time Buy status, indicating limited future availability.

For new designs or system updates requiring this ADC functionality, the ADS8342IBPFBT should be selected as the preferred alternative. Both parts satisfy ROHS3 and REACH compliance requirements, ensuring regulatory alignment for current manufacturing standards. The MSL 2 rating applies to both variants, requiring standard moisture control during storage and handling.

Existing designs currently utilizing the ADS8342IPFBT can transition to the ADS8342IBPFBT without circuit modification, as pin configuration, electrical characteristics, and functional behavior are identical. Procurement should prioritize the ADS8342IBPFBT given its Last Time Buy status, as future availability of either variant cannot be guaranteed.

Frequently Asked Questions (FAQ)

Q: Can the ADS8342IBPFBT be used as a direct replacement for the ADS8342IPFBT in existing designs?

A: Yes. Both devices are electrically and functionally identical. No circuit modifications are required. Pin assignments, supply voltage requirements, input configurations, and output protocols are identical across both part numbers.

Q: What is the difference between ADS8342IPFBT and ADS8342IBPFBT?

A: The primary difference is product lifecycle status. The ADS8342IPFBT is Obsolete, while the ADS8342IBPFBT is Last Time Buy. Electrically and mechanically, both parts are equivalent. The suffix variation reflects manufacturing batch or packaging format designation by Texas Instruments.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ADS8342IPFBT and ADS8342IBPFBT maintain identical ROHS3 compliance and REACH status. MSL ratings are equivalent at MSL 2 (1 Year), requiring identical moisture control protocols during storage and assembly.

Q: What packaging formats are available for the ADS8342IBPFBT?

A: The ADS8342IBPFBT is available in Cut Tape (CT) and Digi-Reel® packaging formats. Both formats contain the same 48-TQFP (7x7) component with identical electrical specifications.

Q: Is the 48-TQFP package the only available form factor?

A: Based on provided specifications, both the ADS8342IPFBT and ADS8342IBPFBT are supplied exclusively in 48-TQFP (7x7) package configuration. No alternative package options are documented for these part numbers.

Q: What supply voltage configuration is required for operation?

A: Both devices require ±5V supply for analog and digital domains. Designs must provide separate regulated ±5V supplies for optimal performance and noise isolation between analog and digital signal paths.
