ADS5481IRGC25 Equivalent & Substitute Parts

Part Overview

The ADS5481IRGC25 is a 16-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for high-speed data acquisition applications. It features a single differential input with an 80 MHz sampling rate and operates with both external and internal reference configurations. The device is packaged in a 64-VQFN (9x9) surface mount package with exposed pad.

The ADS5481IRGC25 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications utilizing this data acquisition component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS5481IRGC25 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:

• 16-bit resolution and 80 MHz sampling rate
• Single differential input configuration
• LVDS parallel data interface
• Pipelined architecture with 1:1 S/H:ADC ratio
• External and internal reference capability
• Analog supply voltage range (3.1V ~ 3.6V, 5V)
• Digital supply voltage range (3V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• 64-VQFN (9x9) package with exposed pad
• Surface mount mounting type

The substitute parts ADS5481IRGCR and ADS5481IRGCT are parametric equivalents that maintain identical functional and electrical specifications. The primary difference between these parts and the main part number is the packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

Both ADS5481IRGCR and ADS5481IRGCT are direct parametric equivalents to the ADS5481IRGC25 and are suitable for substitution in applications requiring 16-bit, 80 MHz pipelined analog-to-digital conversion with differential input and LVDS parallel output.

The primary advantage of selecting ADS5481IRGCR or ADS5481IRGCT is their active product status with Texas Instruments, ensuring ongoing availability and long-term supply chain support compared to the obsolete ADS5481IRGC25. Both substitute parts maintain identical electrical specifications, thermal performance, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The packaging format difference (Tape & Reel for substitutes versus Tube for the main part) affects handling and assembly processes but does not impact electrical or functional performance. Selection between ADS5481IRGCR and ADS5481IRGCT should be based on inventory availability and procurement requirements, as both parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Are ADS5481IRGCR and ADS5481IRGCT fully compatible with ADS5481IRGC25 in existing designs?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications, pin configurations, and package dimensions. Direct substitution is possible without circuit modifications or design changes.

Q: What is the difference between the three part numbers?

A: The ADS5481IRGC25, ADS5481IRGCR, and ADS5481IRGCT are functionally identical 16-bit, 80 MHz pipelined ADCs. The differences are limited to product status (Obsolete vs. Active) and packaging format (Tube vs. Tape & Reel). All three parts share the same base product number ADS5481 and identical electrical characteristics.

Q: Why is the ADS5481IRGC25 marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The availability of active equivalent parts (ADS5481IRGCR and ADS5481IRGCT) ensures continued access to this functionality for new designs and production requirements.

Q: Can I use ADS5481IRGCR or ADS5481IRGCT in high-volume production?

A: Yes. Both parts carry active product status and are available in Tape & Reel packaging, which is standard for automated assembly and high-volume manufacturing. Tape & Reel format provides better handling efficiency and cost optimization for production environments.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level (MSL 3, 168 Hours). Compliance certifications and environmental standards are equivalent across all three part numbers.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: MSL 3 (168 Hours) indicates the component can be exposed to ambient conditions (30°C, 85% relative humidity) for up to 168 hours before soldering without risk of moisture-induced damage. This specification is critical for supply chain handling, storage, and assembly planning.

Q: Should I prefer one substitute part over the other?

A: Selection between ADS5481IRGCR and ADS5481IRGCT should be based on current inventory availability, supplier lead times, and procurement preferences. Both parts are electrically and mechanically identical with no technical advantage of one over the other.
