ADS5542IPAPR Equivalent & Substitute Parts

Part Overview

The ADS5542IPAPR is a 14-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for data acquisition applications requiring single differential input with parallel data interface. The device operates at 80 MSPS sampling rate with internal voltage reference and is housed in a 64-HTQFP surface mount package.

The ADS5542IPAPR carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS5542IPAPR is determined by strict equivalence across the following critical parameters:

• Resolution: 14 bits
• Sampling Rate: 80 MSPS
• Input Configuration: Single differential input
• Data Interface: Parallel
• Architecture: Pipelined
• Reference: Internal
• Supply Voltage Ranges: Analog 3V–3.6V, Digital 3V–3.6V
• Package: 64-PowerTQFP (10×10 mm)
• Operating Temperature: −40°C to +85°C
• RoHS and MSL Compliance: ROHS3 Compliant, MSL 3

The ADS5542IPAP qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (tray versus tube) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The ADS5542IPAP is the manufacturer-recommended substitute for the obsolete ADS5542IPAPR. Both devices are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters.

Selection of the ADS5542IPAP is supported by:

• Active product status ensuring continued availability and manufacturing support
• Full compliance with ROHS3 and REACH requirements
• Identical MSL rating (3, 168 hours) for moisture-sensitive device handling
• Equivalent performance across resolution, sampling rate, supply voltage, and temperature range specifications
• Compatible 64-PowerTQFP package footprint for direct PCB integration

The distinction between tube and tray packaging does not affect electrical performance or functional compatibility. Packaging selection should be based on procurement volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the ADS5542IPAP be used as a direct replacement for the ADS5542IPAPR in existing designs?

A: Yes. The ADS5542IPAP is electrically and mechanically equivalent to the ADS5542IPAPR. Both devices share identical resolution, sampling rate, input configuration, supply voltage requirements, operating temperature range, and package footprint. No circuit modifications are required.

Q: What is the difference between the ADS5542IPAPR and ADS5542IPAP?

A: The primary difference is product status and packaging format. The ADS5542IPAPR is obsolete and supplied in tube packaging, while the ADS5542IPAP is active and supplied in tray packaging. Electrical specifications and performance are identical.

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

A: No. Both parts maintain identical RoHS3 compliance, REACH status, and MSL ratings. No additional qualification or testing is required when transitioning from the obsolete to the active part number.

Q: Does the packaging format (tube versus tray) affect circuit performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical performance and functional characteristics remain unchanged.

Q: What supply voltage range does the ADS5542IPAP support?

A: The ADS5542IPAP operates with analog supply voltage of 3V to 3.6V and digital supply voltage of 3V to 3.6V. Both supplies must remain within these ranges for proper device operation.

Q: Is the ADS5542IPAP suitable for the full −40°C to +85°C temperature range?

A: Yes. The ADS5542IPAP is rated for operation across the full −40°C to +85°C temperature range with no performance degradation within specified electrical parameters.
