ADS1625IPAPR Equivalent & Substitute Parts

Part Overview

The ADS1625IPAPR 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 a 1.25 MHz sampling rate and operates with dual supply voltages (5V analog, 2.7V–3.3V digital). The ADS1625IPAPR is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, redesigns, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS1625IPAPR is determined by strict equivalence across the following critical parameters:

• Resolution & Sampling Rate: 18 bits at 1.25 MHz
• Input Configuration: Single differential input
• Architecture: Sigma-delta ADC topology
• Data Interface: Parallel output
• Supply Voltages: 5V analog and 2.7V–3.3V digital
• Package & Pinout: 64-HTQFP (10x10) surface mount
• Operating Temperature Range: –40°C to +85°C
• Compliance: ROHS3, REACH Unaffected, EAR99

Two substitute parts meet these criteria: ADS1625IPAPT (direct packaging variant) and ADS1626IPAPT (parametric equivalent from the same product family).

Parameter Comparison

Engineering Selection Recommendations

ADS1625IPAPT is the primary substitute for ADS1625IPAPR. Both parts share identical electrical and mechanical specifications; the difference lies in packaging format. ADS1625IPAPR is supplied in tube packaging, while ADS1625IPAPT is supplied in Tape & Reel (TR) format. ADS1625IPAPT is currently in active production status, ensuring long-term availability and supply chain stability.

ADS1626IPAPT is a parametric equivalent substitute. It maintains all critical electrical parameters and physical package dimensions identical to ADS1625IPAPR. The ADS1626 represents an evolution within the same product family and is actively manufactured. Selection between ADS1625IPAPT and ADS1626IPAPT depends on design requirements and supply chain considerations; both are functionally interchangeable within the specified parameter set.

Both substitute parts carry ROHS3 compliance, REACH Unaffected status, and EAR99 export classification, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can ADS1625IPAPT directly replace ADS1625IPAPR in existing designs?

A: Yes. ADS1625IPAPT is electrically and mechanically identical to ADS1625IPAPR. The only difference is packaging format (Tape & Reel versus tube). No circuit modifications are required.

Q: What is the difference between ADS1625IPAPT and ADS1626IPAPT?

A: Both parts are parametric equivalents with identical electrical specifications, resolution, sampling rate, input configuration, and package. The ADS1626 is a newer variant within the same product family. Selection depends on availability and supply chain strategy.

Q: Are the pinouts identical across all three parts?

A: Yes. All three parts use the 64-HTQFP (10x10) package with identical pinout configuration. PCB layout and schematic connections require no modification.

Q: What is the significance of the packaging difference (tube vs. Tape & Reel)?

A: Tube packaging (ADS1625IPAPR) is used for lower-volume or legacy applications. Tape & Reel packaging (ADS1625IPAPT, ADS1626IPAPT) is standard for automated assembly and higher-volume production. Both formats contain the same die and deliver identical performance.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts carry identical RoHS3 compliance, REACH Unaffected status, MSL rating (3, 168 hours), and EAR99 export classification.

Q: Why is ADS1625IPAPR marked as obsolete?

A: ADS1625IPAPR has been superseded by active production variants (ADS1625IPAPT and ADS1626IPAPT). Texas Instruments no longer manufactures the tube-packaged version. Existing inventory is available, but new designs should specify the active alternatives.
