THS1041IPW Equivalent & Substitute Parts

Part Overview

The THS1041IPW is a 10-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for single-channel data acquisition applications. It features a 40 MHz sampling rate with differential and single-ended input capability, housed in a 28-TSSOP surface mount package. The device operates on 3V to 3.6V supply voltage for both analog and digital domains.

The THS1041IPW is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the THS1041IPW is determined by the following critical parameters:

Core Functional Parameters:

• Resolution: 10 bits
• Sampling Rate: 40 MHz
• Number of Inputs: 1
• Input Type: Differential and Single Ended capability
• Architecture: Pipelined
• Data Interface: Parallel
• Package: 28-TSSOP

Supply Voltage Compatibility:

• Analog Supply: 3V ~ 3.6V range
• Digital Supply: 3V ~ 3.6V range

Environmental & Compliance:

• Operating Temperature: -40°C ~ 85°C
• RoHS3 Compliance
• Surface Mount configuration

The ADC10040CIMTX/NOPB qualifies as a substitute based on matching all core functional parameters, identical package specification, and compatible operating temperature range. Both devices share the same base product architecture (10-bit pipelined ADC, 40 MHz sampling, single input, parallel interface) and physical form factor.

Engineering Selection Recommendations

The ADC10040CIMTX/NOPB is the qualified substitute for the obsolete THS1041IPW. Selection is based on the following engineering criteria:

Functional Equivalence: Both devices are 10-bit pipelined analog-to-digital converters with identical sampling rates (40 MHz), single-channel input configuration, and parallel data interface. Core signal processing architecture and performance characteristics are equivalent.

Package Compatibility: Both components use the 28-TSSOP surface mount package with identical physical dimensions (0.173" width, 4.40mm). PCB layout and mechanical integration remain unchanged.

Supply Voltage: The ADC10040CIMTX/NOPB features expanded supply voltage ranges (2.7V ~ 3.6V analog, 2.5V ~ 3.6V digital) compared to the THS1041IPW (3V ~ 3.6V both domains). This provides enhanced flexibility in power supply design while maintaining full compatibility with the original specification.

Compliance & Certification: Both devices are ROHS3 compliant and operate across the identical temperature range (-40°C ~ 85°C). The substitute maintains all regulatory and environmental requirements of the original component.

Product Status: The ADC10040CIMTX/NOPB is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete THS1041IPW.

Frequently Asked Questions (FAQ)

Q: Can the ADC10040CIMTX/NOPB be used as a direct replacement for the THS1041IPW?

A: Yes. Both devices share identical resolution (10 bits), sampling rate (40 MHz), input configuration (1 channel, differential/single-ended), architecture (pipelined), and package specification (28-TSSOP). Functional and physical compatibility is complete.

Q: What is the difference in supply voltage specifications?

A: The ADC10040CIMTX/NOPB accepts analog supply from 2.7V to 3.6V and digital supply from 2.5V to 3.6V, compared to the THS1041IPW which requires 3V to 3.6V for both domains. The substitute has wider voltage tolerance, making it more flexible for power supply design while remaining compatible with the original 3V to 3.6V operating point.

Q: Are there packaging differences between these parts?

A: No. Both components use the 28-TSSOP surface mount package with identical physical dimensions. PCB footprints, solder pad layouts, and mechanical mounting are equivalent. No design changes are required.

Q: Why is the THS1041IPW obsolete?

A: The THS1041IPW has been discontinued by Texas Instruments. The ADC10040CIMTX/NOPB represents the active product line continuation with equivalent specifications and improved supply voltage flexibility.

Q: Are both devices RoHS compliant?

A: Yes. Both the THS1041IPW and ADC10040CIMTX/NOPB are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the difference in moisture sensitivity?

A: The THS1041IPW has MSL 1 (Unlimited), while the ADC10040CIMTX/NOPB has MSL 3 (168 Hours). The substitute requires standard moisture control during storage and handling per IPC-A-610 guidelines for MSL 3 components.
