ADS8517IDW Equivalent & Substitute Parts

Part Overview

The ADS8517IDW is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 200 kSPS sampling rate and operates with external or internal voltage references. The device is packaged in a 28-SOIC surface mount package.

The ADS8517IDW is classified as obsolete. Identifying equivalent and 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 of the ADS8517IDW is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

• Resolution: 16-bit ADC
• Sampling Rate: 200 kSPS
• Input Configuration: Single-ended, 1 input channel
• Data Interface: SPI and Parallel support
• Architecture: SAR-based conversion
• Reference Configuration: External and internal reference capability
• Supply Voltage Ranges: Analog 5V, Digital 1.65V ~ 5.5V
• Operating Temperature Range: -40°C ~ 85°C
• Package: 28-SOIC form factor
• Compliance: ROHS3 Compliant, MSL Level 2

The ADS8517IBDW meets all these criteria and is designated as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The ADS8517IBDW is the direct equivalent substitute for the ADS8517IDW. Both parts are manufactured by Texas Instruments and share identical electrical specifications and mechanical packaging. The primary distinction is product status: the ADS8517IDW is obsolete, while the ADS8517IBDW maintains active production status.

For new designs or ongoing production requiring a 16-bit, 200 kSPS single-ended ADC with SAR architecture and 28-SOIC packaging, the ADS8517IBDW is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ADS8517IBDW be used as a direct replacement for the ADS8517IDW?

A: Yes. The ADS8517IBDW is electrically and mechanically identical to the ADS8517IDW. All electrical parameters, pin configurations, and package dimensions are equivalent. The primary difference is product lifecycle status.

Q: What is the difference between the ADS8517IDW and ADS8517IBDW?

A: The ADS8517IDW is obsolete, while the ADS8517IBDW is in active production. The packaging differs (the substitute is supplied in Tube packaging), but the die and electrical performance are identical.

Q: Are there any pin compatibility concerns when substituting these parts?

A: No. Both parts use the 28-SOIC package with identical pinouts. PCB layouts and socket designs require no modification.

Q: Do both parts support the same supply voltage ranges?

A: Yes. Both the ADS8517IDW and ADS8517IBDW operate with analog supply at 5V and digital supply ranging from 1.65V to 5.5V.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with MSL Level 2 (1 Year) moisture sensitivity ratings. REACH and ECCN classifications are identical.

Q: What data interfaces are supported?

A: Both parts support SPI and Parallel data interfaces, providing flexibility in system integration.
