ADS8322Y/2K Equivalent & Substitute Parts

Part Overview

The ADS8322Y/2K is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring single-channel conversion with SAR architecture. This device operates at 500 kSPS sampling rate and is housed in a 32-TQFP surface mount package. The part is currently in active production status with ROHS3 compliance and full REACH compliance. Substitute parts are identified when inventory constraints or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS8322Y/2K are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 16 Bit
• Sampling Rate: 500 kSPS
• Number of Inputs: 1
• Input Type: Pseudo-Differential, Single Ended
• Architecture: SAR
• Data Interface: Parallel
• Supply Voltage (Analog & Digital): 5V
• Operating Temperature Range: -40°C to 85°C
• Package: 32-TQFP (5x5)
• Mounting Type: Surface Mount
• Base Product Number: ADS8322

The identified substitutes (ADS8322Y/250 and ADS8322YB/250) maintain complete parametric alignment with the primary part number across all specified dimensions. Differences in packaging designations (tape reel specifications) do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (ADS8322Y/2K, ADS8322Y/250, and ADS8322YB/250) are active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is determined by availability and packaging reel specifications rather than functional differences.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The MSL rating of 3 (168 hours) applies uniformly across all variants, establishing identical moisture handling requirements during storage and assembly operations.

Frequently Asked Questions (FAQ)

Q: Can ADS8322Y/250 be used as a direct replacement for ADS8322Y/2K?

A: Yes. Both parts share identical electrical specifications, pin configurations, and package dimensions (32-TQFP 5x5). The difference in part number suffix relates to tape reel specifications only and does not affect functional compatibility or circuit performance.

Q: What is the difference between ADS8322Y/250 and ADS8322YB/250?

A: Both parts are parametrically equivalent with identical electrical and mechanical characteristics. The difference in designation (Y versus YB) reflects manufacturing or packaging line variations but does not impact functional performance or compatibility.

Q: Are all three parts suitable for the same PCB assembly process?

A: Yes. All three variants use identical 32-TQFP (5x5) surface mount packaging with the same pin layout, footprint, and soldering requirements. MSL rating of 3 (168 hours) applies uniformly across all parts.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status, identical to the primary part number. No additional compliance verification is required when substituting between these part numbers.

Q: Can I mix different part numbers in the same production batch?

A: Yes. Since all three parts are parametrically identical with the same electrical performance, pin configuration, and package specifications, they can be used interchangeably within the same design without circuit modification or re-qualification.
