ADS8329IPWG4 Equivalent & Substitute Parts

Part Overview

The ADS8329IPWG4 is a 16-bit Analog to Digital Converter (ADC) with a single differential or single-ended input, operating at 1 Megasample per second (1M SPS). It features a Successive Approximation Register (SAR) architecture with external reference capability and is housed in a 16-TSSOP surface mount package. The device is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the ADS8329IPWG4 is determined by strict equivalence across the following critical parameters:

  • Resolution: 16-bit ADC architecture
  • Sampling Rate: 1M SPS operation
  • Input Configuration: Single input with differential and single-ended capability
  • Interface Protocol: SPI digital communication
  • Converter Architecture: SAR topology
  • Reference Configuration: External reference requirement
  • Supply Voltages: 5V analog supply and 1.65V ~ 5.5V digital supply compatibility
  • Package Footprint: 16-TSSOP form factor with identical pin configuration
  • Operating Temperature: -40°C ~ 85°C range

The ADS8329IPW meets all substitution criteria as a direct equivalent part from the same manufacturer base product line (ADS8329).

Engineering Selection Recommendations

The ADS8329IPW is the direct substitute for the ADS8329IPWG4. Both parts share identical electrical specifications, pin configuration, and package footprint. The primary distinction is product status and regulatory compliance: the ADS8329IPWG4 is discontinued, while the ADS8329IPW maintains active production status. Additionally, the ADS8329IPW carries ROHS3 compliance, whereas the ADS8329IPWG4 is RoHS non-compliant. For new designs or ongoing procurement, the ADS8329IPW is the appropriate selection due to its active availability and improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the ADS8329IPW be used as a direct replacement for the ADS8329IPWG4 in existing designs?

A: Yes. The ADS8329IPW is electrically and mechanically identical to the ADS8329IPWG4. Pin configuration, package footprint, and all functional parameters are equivalent. No circuit modifications are required.

Q: What is the difference between the ADS8329IPWG4 and ADS8329IPW part numbers?

A: Both parts are from the same ADS8329 base product family. The suffix differences relate to packaging and manufacturing batches. The ADS8329IPW is the active production variant with current availability.

Q: Are there any compliance differences between these parts?

A: Yes. The ADS8329IPW is ROHS3 compliant, while the ADS8329IPWG4 is RoHS non-compliant. For applications requiring RoHS compliance, the ADS8329IPW is the appropriate choice.

Q: Will the ADS8329IPW work with the same PCB layout and firmware as the ADS8329IPWG4?

A: Yes. Identical package type (16-TSSOP), pin configuration, and electrical specifications ensure full compatibility with existing PCB designs and firmware implementations.

Q: What is the packaging difference between these parts?

A: The ADS8329IPW is supplied in Tube packaging, while the ADS8329IPWG4 packaging specification is not provided. Both use the same 16-TSSOP surface mount package type.
