ADS1626IPAPRG4 Equivalent & Substitute Parts

Part Overview

The ADS1626IPAPRG4 is an 18-bit analog-to-digital converter manufactured by Texas Instruments, designed for single-channel differential input data acquisition applications. This device features a sigma-delta architecture with 1.25M samples per second sampling rate and operates with dual supply voltages (5V analog, 2.7V–3.3V digital). The part is currently classified as obsolete, making identification of equivalent and substitute components essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the ADS1626IPAPRG4 is determined by strict equivalence across the following parameters: resolution (18 bits), sampling rate (1.25M samples/second), single differential input, parallel data interface, sigma-delta architecture, dual supply voltage requirements (5V analog and 2.7V–3.3V digital), operating temperature range (−40°C to +85°C), and identical package specification (64-HTQFP 10×10 surface mount).

The substitute parts identified—ADS1626IPAPT and ADS1625IPAPT—maintain all electrical and mechanical parameters required for direct functional replacement. Both parts share the same base architecture, input configuration, sampling characteristics, and physical packaging. The primary distinction between substitutes lies in product status and regulatory compliance certifications rather than electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both ADS1626IPAPT and ADS1625IPAPT are suitable substitutes for the obsolete ADS1626IPAPRG4 based on complete electrical and mechanical parameter equivalence. Selection between the two substitute options should prioritize product availability and regulatory compliance requirements.

ADS1626IPAPT provides direct part-number continuity with the original design while offering active product status and ROHS3 compliance. This option is recommended for designs requiring minimal documentation changes and maximum compatibility assurance.

ADS1625IPAPT offers equivalent electrical performance and active product status with ROHS3 compliance. Higher inventory availability (2276 units) may provide procurement advantages for high-volume applications.

Both substitutes maintain identical packaging, thermal characteristics, and supply voltage specifications, ensuring PCB-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ADS1626IPAPT and ADS1625IPAPT be used interchangeably with ADS1626IPAPRG4?

A: Yes. Both substitute parts maintain identical electrical specifications across resolution, sampling rate, input configuration, supply voltages, operating temperature range, and package format. No circuit modifications are required for substitution.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates ongoing manufacturer support, availability through distribution channels, and continued compliance with current regulatory standards. Obsolete status indicates the original part is no longer manufactured or supported by Texas Instruments.

Q: Are there any compliance differences between the substitutes?

A: The main part (ADS1626IPAPRG4) is RoHS non-compliant. Both substitutes (ADS1626IPAPT and ADS1625IPAPT) are ROHS3 compliant. All three parts maintain identical MSL ratings and REACH unaffected status.

Q: Does the 64-HTQFP package remain the same across all three parts?

A: Yes. All three parts use the 64-HTQFP (10×10) surface mount package with identical pinout and mechanical specifications.

Q: What inventory considerations should influence part selection?

A: ADS1625IPAPT offers significantly higher inventory availability (2276 units) compared to ADS1626IPAPT (900 units). For high-volume production, ADS1625IPAPT may provide supply chain advantages.
