Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADS5546IRGZRG4 is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• 14-bit resolution
• Single differential input configuration
• Pipelined architecture
• 48-VQFN (7x7) package with exposed pad
• 3V to 3.6V analog and digital supply voltage range
• External and internal reference capability
• LVDS and parallel data interface support
• Surface mount mounting type
• Operating temperature range of -40°C to 85°C

Allowable Variation:

• Sampling rate: The ADS5546IRGZRG4 operates at 190 MHz. Substitute parts may operate at equal or higher sampling rates while maintaining all other electrical and mechanical specifications.
• Product status: Active status substitutes are preferred over obsolete parts for long-term availability.
• Packaging format: Tape & Reel (TR) packaging is functionally equivalent to the original packaging for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

ADS5547IRGZR is classified as a direct manufacturer substitute. This part maintains identical electrical specifications to the ADS5546IRGZRG4 with the exception of an increased sampling rate of 210 MHz versus 190 MHz. The higher sampling rate provides enhanced performance capability while preserving all other functional parameters. The ADS5547IRGZR carries active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings.

ADS5546IRGZT is classified as a parametric equivalent. This part shares the identical base product number (ADS5546) and maintains all electrical and mechanical specifications including the 190 MHz sampling rate. The primary distinction is active product status compared to the obsolete ADS5546IRGZRG4. The ADS5546IRGZT is supplied in Tape & Reel packaging format, which is functionally equivalent for component selection. ROHS3 compliance and moisture sensitivity specifications are identical.

Both substitute parts are suitable for applications requiring the ADS5546IRGZRG4 specification. Selection between substitutes should be based on application sampling rate requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the ADS5547IRGZR be used as a direct replacement for the ADS5546IRGZRG4?

A: Yes. The ADS5547IRGZR maintains all critical electrical and mechanical specifications. The sampling rate increase from 190 MHz to 210 MHz represents enhanced performance capability and does not create incompatibility with designs specified for the ADS5546IRGZRG4.

Q: What is the difference between the ADS5547IRGZR and ADS5546IRGZT?

A: The ADS5547IRGZR operates at 210 MHz sampling rate, while the ADS5546IRGZT operates at 190 MHz. Both are active products with identical electrical specifications in all other parameters. Selection depends on application sampling rate requirements.

Q: Are the packaging formats interchangeable?

A: Yes. The ADS5546IRGZRG4 and both substitute parts use the 48-VQFN (7x7) package with exposed pad. Tape & Reel (TR) packaging format is functionally equivalent for component selection and PCB assembly purposes.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both ADS5547IRGZR and ADS5546IRGZT are ROHS3 compliant with identical moisture sensitivity levels (MSL 3, 168 Hours) and REACH unaffected status.

Q: Why is the ADS5546IRGZRG4 listed as obsolete?

A: The ADS5546IRGZRG4 has reached end-of-life status. The substitute parts ADS5547IRGZR and ADS5546IRGZT are active products recommended for new designs and ongoing procurement requirements.

Q: Can both substitute parts be used interchangeably in the same design?

A: Yes, provided the application does not require the specific 210 MHz sampling rate of the ADS5547IRGZR. For applications with sampling rate flexibility, both parts are electrically and mechanically compatible.
