ADS8482IBRGZR Equivalent & Substitute Parts

Part Overview

The ADS8482IBRGZR is an 18-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for precision data acquisition applications. This single-input SAR (Successive Approximation Register) ADC operates with a 1 MHz sampling rate and supports both external and internal voltage references. The device is housed in a 48-VQFN (7x7) package with exposed pad for surface mount applications.

The ADS8482IBRGZR is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS8482IBRGZR is determined by strict equivalence across the following critical parameters:

• Resolution: 18 bits
• Sampling Rate: 1 MHz
• Input Configuration: Single differential input
• Architecture: SAR topology
• Data Interface: Parallel output
• Reference Options: External and internal reference support
• Supply Voltages: Analog 5V, Digital 2.7V ~ 5.25V
• Package: 48-VQFN (7x7) with exposed pad
• Temperature Range: -40°C ~ 85°C
• Compliance: ROHS3 compliant, MSL 2 rating

The ADS8482IBRGZT qualifies as a parametric equivalent based on identical electrical specifications and package footprint. The primary distinction is packaging format (Tape & Reel versus bulk) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The ADS8482IBRGZT is a direct parametric equivalent to the ADS8482IBRGZR. Both devices share identical electrical specifications, pin configuration, and package footprint. The substitution is valid from a functional and mechanical standpoint.

Product Status Considerations:

The ADS8482IBRGZR is discontinued at DiGi Electronics, while the ADS8482IBRGZT carries a "Not For New Designs" status. Both devices are legacy products. For new designs requiring 18-bit SAR ADC functionality with single differential input and 1 MHz sampling rate, evaluation of current-generation alternatives from Texas Instruments is recommended to ensure long-term supply chain stability and access to manufacturing support.

Compliance:

Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the ADS8482IBRGZT directly replace the ADS8482IBRGZR in existing designs?

A: Yes. The ADS8482IBRGZT is electrically and mechanically equivalent. Pin configuration, package footprint, and electrical performance are identical. The primary difference is packaging format (Tape & Reel versus bulk).

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

A: The suffix designates packaging format. The "R" in ADS8482IBRGZR indicates bulk packaging, while the "T" in ADS8482IBRGZT indicates Tape & Reel (TR) packaging. Electrical specifications are identical.

Q: Are there any supply voltage or temperature range differences?

A: No. Both parts operate with identical analog supply voltage (5V), digital supply voltage range (2.7V ~ 5.25V), and temperature range (-40°C ~ 85°C).

Q: Do both parts support the same reference voltage options?

A: Yes. Both the ADS8482IBRGZR and ADS8482IBRGZT support external and internal reference voltage configurations.

Q: What is the MSL rating, and does it affect substitution?

A: Both parts carry MSL 2 (1 Year) rating. This indicates moisture sensitivity level and shelf life requirements. No substitution impact exists between these parts.

Q: Are there RoHS compliance differences?

A: No. Both parts are ROHS3 compliant and suitable for applications requiring environmental regulation adherence.

Q: Why is the ADS8482IBRGZR discontinued?

A: Product discontinuation is a manufacturer lifecycle decision. The ADS8482IBRGZT remains available with "Not For New Designs" status, indicating limited future availability. For ongoing production, alternative current-generation ADC solutions should be evaluated.
