THS1031IPWG4 Equivalent & Substitute Parts

Part Overview

The THS1031IPWG4 is a 10-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for data acquisition applications requiring single or differential input processing. This device operates across a 3V to 5.5V supply range with a 30 MHz sampling rate and is housed in a 28-TSSOP package.

The THS1031IPWG4 has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1031IPWG4 is determined by the following core parameters:

• 10-bit resolution requirement
• Pipelined architecture for consistent conversion performance
• Single input channel configuration
• Parallel data interface compatibility
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance for regulatory alignment

The ADS825E qualifies as a manufacturer-recommended substitute based on matching resolution, architecture, input configuration, data interface, temperature range, and compliance certifications. Differences in sampling rate (40 MHz vs. 30 MHz), supply voltage specifications (5V fixed vs. 3V–5.5V range), and package type (28-SSOP vs. 28-TSSOP) must be evaluated within the context of the specific application circuit design.

Parameter Comparison

Engineering Selection Recommendations

The ADS825E is the manufacturer-recommended substitute for the obsolete THS1031IPWG4. Both devices maintain ROHS3 compliance and are manufactured by Texas Instruments, ensuring regulatory alignment and supply chain continuity.

The ADS825E is currently in active production status, providing long-term availability and support compared to the obsolete THS1031IPWG4. The substitute device maintains identical resolution, architecture, input configuration, and data interface specifications.

Circuit design modifications are required to accommodate the ADS825E's fixed 5V supply requirement, as the THS1031IPWG4 supports a broader 3V to 5.5V range. The 28-SSOP package footprint differs from the 28-TSSOP package; PCB layout adjustments are necessary. The higher sampling rate of the ADS825E (40 MHz) does not create compatibility constraints in applications designed for the 30 MHz THS1031IPWG4.

Frequently Asked Questions (FAQ)

Q: Can the ADS825E directly replace the THS1031IPWG4 without circuit modifications?

A: No. While both devices share identical resolution, architecture, and input specifications, the ADS825E requires a fixed 5V supply, whereas the THS1031IPWG4 operates across 3V to 5.5V. Supply circuit modifications are necessary. Additionally, the package footprint differs (28-SSOP vs. 28-TSSOP), requiring PCB layout changes.

Q: What is the significance of the different sampling rates (30 MHz vs. 40 MHz)?

A: The ADS825E's higher sampling rate does not create backward compatibility issues. Applications designed for the THS1031IPWG4's 30 MHz sampling rate will function with the ADS825E. The increased sampling capability provides additional performance margin.

Q: Are both devices RoHS compliant?

A: Yes. Both the THS1031IPWG4 and ADS825E are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the THS1031IPWG4 listed as obsolete?

A: The THS1031IPWG4 has reached end-of-life status. Texas Instruments recommends the ADS825E as the active substitute for new designs and ongoing production support.

Q: What are the package differences between 28-TSSOP and 28-SSOP?

A: Both are 28-pin small-outline packages with different body widths. The 28-TSSOP has a 4.40mm width, while the 28-SSOP has a 5.30mm width. PCB footprints and land patterns are not interchangeable; layout redesign is required for substitution.
