ADS1252UG4 Equivalent & Substitute Parts

Part Overview

The ADS1252UG4 is a 24-bit Sigma-Delta analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input data acquisition applications. The device features a 40 kSPS sampling rate, external reference configuration, and operates from dual 5V supply rails across the temperature range of -40°C to 85°C in an 8-SOIC surface mount package.

The ADS1252UG4 is discontinued at DiGi Electronics. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS1252UG4 is determined by strict equivalence across the following critical parameters:

• 24-bit resolution requirement
• 40 kSPS sampling rate specification
• Single differential input channel configuration
• SPI serial data interface
• Sigma-Delta converter architecture
• External reference input requirement
• Dual 5V supply voltage compatibility
• 8-SOIC package footprint and pinout
• Operating temperature range of -40°C to 85°C
• Surface mount technology

The ADS1252U meets all specified parameters and serves as a direct substitute. The primary distinction between the main part and substitute is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The ADS1252U is the manufacturer-recommended substitute for the ADS1252UG4. Both devices are manufactured by Texas Instruments and maintain identical electrical specifications, pinout compatibility, and package dimensions. The ADS1252U carries active product status with confirmed inventory availability, whereas the ADS1252UG4 is discontinued.

Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with current manufacturing and environmental standards. The ADS1252U is available in tube packaging, whereas the original part was supplied in tape and reel format. This packaging difference does not affect electrical performance or functional integration into existing designs.

Frequently Asked Questions (FAQ)

Q: Can the ADS1252U be used as a direct replacement for the ADS1252UG4?

A: Yes. The ADS1252U is electrically and functionally identical to the ADS1252UG4. Both devices share the same 24-bit resolution, 40 kSPS sampling rate, SPI interface, external reference configuration, and 8-SOIC package footprint. Pin-for-pin compatibility is maintained.

Q: Are there differences in supply voltage requirements between these parts?

A: No. Both the ADS1252UG4 and ADS1252U require identical dual 5V supply voltages for analog and digital circuits and operate across the same -40°C to 85°C temperature range.

Q: Does the packaging format change affect circuit board design?

A: No. The packaging format difference (tape and reel versus tube) does not affect the physical component dimensions, pinout, or electrical characteristics. The 8-SOIC package footprint remains identical.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the ADS1252UG4 and ADS1252U are ROHS3 compliant and carry identical MSL ratings of 2 (1 Year), meeting current manufacturing and environmental requirements.

Q: What is the primary reason to transition from ADS1252UG4 to ADS1252U?

A: The ADS1252UG4 is discontinued at DiGi Electronics. The ADS1252U maintains active product status with confirmed inventory availability, ensuring continued supply chain access for new production and design implementations.
