ADS8322YB/2K Equivalent & Substitute Parts

Part Overview

The ADS8322YB/2K is a 16-bit Analog to Digital Converter (ADC) from Texas Instruments' microPOWER™ series, housed in a 32-TQFP (5x5) surface mount package. This component features a single pseudo-differential or single-ended input with a 500 kSPS sampling rate and SAR architecture, operating from 5V analog and digital supplies across the -40°C to 85°C temperature range.

The ADS8322YB/2K is classified as Obsolete. Locating equivalent or substitute parts is necessary to support ongoing production, maintenance, or redesign efforts where this component is specified in existing designs.

Substitute Part Grouping Explanation

Substitution of the ADS8322YB/2K is determined by strict equivalence across the following critical parameters:

  • Resolution & Sampling Rate: 16-bit, 500 kSPS
  • Input Configuration: 1 input, pseudo-differential or single-ended
  • Data Interface: Parallel
  • Architecture: SAR with 1:1 S/H:ADC ratio
  • Supply Voltages: 5V analog and digital
  • Package: 32-TQFP (5x5) surface mount
  • Temperature Range: -40°C to 85°C
  • Compliance: ROHS3, MSL 3

All substitute parts listed maintain identical electrical and mechanical specifications. Differences are limited to product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Engineering Selection Recommendations

Primary Recommendation: ADS8322YB/250 is the manufacturer-recommended substitute. It maintains identical electrical and mechanical specifications to the ADS8322YB/2K while offering Active product status and improved availability. The packaging format difference (Tape & Reel) reflects current manufacturing standards and does not affect functional compatibility.

Alternative Options: ADS8322Y/2K and ADS8322Y/250 are parametric equivalents with Active status. These parts are functionally interchangeable with the original specification and provide additional inventory availability.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 3 (168 Hours) rating, ensuring compatibility with standard PCB assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can ADS8322YB/250 directly replace ADS8322YB/2K in existing designs? A: Yes. Both parts are electrically and mechanically identical. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard). No design modifications are required.

Q: What is the difference between ADS8322YB and ADS8322Y variants? A: The provided data indicates both variants maintain identical electrical specifications, resolution, sampling rate, input configuration, and package. Differences are limited to product status and availability.

Q: Does the Tape & Reel packaging affect PCB assembly compatibility? A: No. Tape & Reel is a standard packaging format for surface mount components and is fully compatible with automated PCB assembly equipment. The 32-TQFP (5x5) package footprint remains unchanged.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 3 (168 Hours) rating, meeting standard environmental and assembly process requirements.

Q: What does the "/2K" and "/250" designation indicate? A: These designations represent different packaging quantities. Both variants are electrically identical and functionally interchangeable.
