ADS8284IBRGCT Equivalent & Substitute Parts

Part Overview

The ADS8284IBRGCT is an 18-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for multi-channel data acquisition applications. This device features 4 pseudo-differential inputs, a 1 MHz sampling rate, and operates with external or internal voltage references. The part is packaged in a 64-VQFN (9x9) surface mount configuration with an exposed pad.

The ADS8284IBRGCT carries a product status of "Not For New Designs," indicating that Texas Instruments has discontinued active development and support for this component. Organizations requiring this functionality for new applications or seeking to maintain existing inventory should evaluate equivalent substitute parts that maintain electrical and mechanical compatibility while potentially offering improved availability or updated product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS8284IBRGCT are determined by strict equivalence across the following critical parameters:

• Resolution: 18-bit ADC
• Sampling Rate: 1 MHz per second
• Input Configuration: 4 pseudo-differential inputs
• Architecture: SAR-based analog-to-digital conversion
• Data Interface: Parallel output
• Reference Configuration: External and internal reference support
• Supply Voltages: 5V analog supply and 2.7V–3.3V digital supply
• Operating Temperature: -40°C to 85°C
• Package: 64-VQFN (9x9) with exposed pad
• Compliance: ROHS3 compliant, REACH unaffected

The ADS8284IBRGCR is identified as a parametric equivalent based on identical electrical specifications and mechanical packaging. The primary distinction between these parts is packaging format: the main part (ADS8284IBRGCT) is supplied in Cut Tape (CT) & Digi-Reel format, while the substitute (ADS8284IBRGCR) is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

Both the ADS8284IBRGCT and ADS8284IBRGCR are classified as "Not For New Designs" by Texas Instruments. This status indicates that these components are no longer recommended for incorporation into new product development. However, both parts maintain full electrical and mechanical compatibility, making them suitable for replacement or maintenance applications where existing designs require component substitution.

Selection between these two parts should be based on packaging and supply chain requirements:

• ADS8284IBRGCT (Cut Tape & Digi-Reel): Suitable for lower-volume applications or situations requiring flexible quantity handling.
• ADS8284IBRGCR (Tape & Reel): Appropriate for higher-volume production runs where standard reel packaging aligns with automated assembly processes.

Both parts comply with ROHS3 standards and carry identical MSL ratings, ensuring equivalent environmental and handling requirements. Current inventory availability should be verified with component suppliers, as stock levels may vary between packaging formats.

Frequently Asked Questions (FAQ)

Q: Can ADS8284IBRGCR be used as a direct replacement for ADS8284IBRGCT?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format (Cut Tape vs. Tape & Reel). They share the same pinout, electrical specifications, and performance characteristics, making them fully interchangeable at the component level.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components on individual tape segments, typically used for lower-volume orders or manual assembly. Tape & Reel packaging supplies components on continuous reels, optimized for automated pick-and-place assembly in high-volume manufacturing. Both formats contain the same component; the difference is in supply and handling methodology.

Q: Are there any differences in lead times or availability between these two part numbers?

A: Lead times and availability depend on current supplier inventory and market conditions. While both parts are manufactured by Texas Instruments with identical specifications, supply levels may differ. Contact your component distributor for current stock status and delivery timelines for each packaging format.

Q: Does the "Not For New Designs" status affect the usability of these parts?

A: The "Not For New Designs" status indicates that Texas Instruments has discontinued active development and support for this product line. Existing inventory remains functional and suitable for replacement or maintenance applications. However, for new product development, evaluation of current-generation ADC alternatives from Texas Instruments is recommended.

Q: Are both parts RoHS compliant?

A: Yes. Both ADS8284IBRGCT and ADS8284IBRGCR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry an MSL (Moisture Sensitivity Level) rating of 3 with a 168-hour floor life. This rating specifies handling and storage requirements to prevent moisture-induced damage during assembly. Components must be stored in controlled humidity environments and used within the specified floor life after opening the moisture barrier bag.
