THS1030CDWG4 Equivalent & Substitute Parts

Part Overview

The THS1030CDWG4 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 features a 1 MHz sampling rate and operates across a 3V to 5.5V supply range in a 28-SOIC package.

The THS1030CDWG4 has reached obsolete product status. Identifying qualified substitute components is essential for design continuity, procurement planning, and system reliability in applications where this device is currently deployed or specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1030CDWG4 is determined by the following core parameters:

• 10-bit resolution requirement
• Pipelined architecture
• Single input channel configuration
• Parallel data interface
• External and internal reference capability
• Surface mount package compatibility

The ADS825E qualifies as a manufacturer-recommended substitute based on matching resolution, architecture, input configuration, data interface, and reference options. Both devices maintain pipelined ADC topology with identical input flexibility and reference architecture.

Parameter Comparison

Engineering Selection Recommendations

The ADS825E is the manufacturer-recommended substitute for the THS1030CDWG4. Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The ADS825E offers enhanced performance with a 40 MSPS sampling rate compared to the THS1030CDWG4's 30 MSPS capability. The substitute operates at fixed 5V supply levels rather than the original device's 3V to 5.5V range, requiring verification of power supply architecture in target applications.

The ADS825E is packaged in 28-SSOP format versus the original 28-SOIC package. PCB layout modifications are necessary to accommodate the different package footprint and pin spacing (5.30mm versus 7.50mm width).

The ADS825E supports an extended operating temperature range of -40°C to 85°C, providing broader environmental coverage compared to the original 0°C to 70°C specification.

Frequently Asked Questions (FAQ)

Q: Can the ADS825E directly replace the THS1030CDWG4 without circuit modifications?

A: The ADS825E requires PCB layout changes due to package differences (28-SSOP versus 28-SOIC). Power supply architecture must be evaluated, as the substitute operates at fixed 5V rather than the original 3V to 5.5V range. Pin-to-pin compatibility must be verified against specific application schematics.

Q: What are the key functional differences between these devices?

A: Both devices share identical 10-bit resolution, pipelined architecture, single-channel input configuration, and parallel data interface. The ADS825E provides higher sampling rate performance (40 MSPS versus 30 MSPS) and extended temperature range (-40°C to 85°C versus 0°C to 70°C).

Q: Are there supply voltage constraints when substituting?

A: The THS1030CDWG4 accepts 3V to 5.5V analog and digital supplies. The ADS825E requires fixed 5V supplies. Applications operating at 3V or 3.3V require voltage regulation or alternative solutions.

Q: How do package differences affect substitution feasibility?

A: The THS1030CDWG4 uses 28-SOIC packaging (7.50mm width) while the ADS825E uses 28-SSOP packaging (5.30mm width). These packages have different footprints and pin spacing, requiring PCB redesign for mechanical and electrical compatibility.

Q: What compliance certifications apply to both devices?

A: Both the THS1030CDWG4 and ADS825E are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
