ADS5545IRGZRG4 Equivalent & Substitute Parts

Part Overview

The ADS5545IRGZRG4 is a 14-bit pipelined analog-to-digital converter manufactured by Texas Instruments, designed for high-speed data acquisition applications. This device features a single differential input, 170 MHz sampling rate, and operates from 3V to 3.6V supply voltage. The component is housed in a 48-VQFN (7x7) package with exposed pad and is ROHS3 compliant.

The ADS5545IRGZRG4 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements.

Substitute Part Grouping Explanation

Substitute parts for the ADS5545IRGZRG4 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant or within acceptable ranges for direct substitution:

Resolution: 14 bits
Number of inputs: 1 differential input
Data interface: LVDS - Parallel, Parallel
Architecture: Pipelined configuration
Supply voltage range: 3V ~ 3.6V (both analog and digital)
Operating temperature range: -40°C ~ 85°C
Package type: 48-VFQFN Exposed Pad
Mounting type: Surface Mount
Compliance: ROHS3, REACH Unaffected

Sampling rate variations are permitted within the product family when all other electrical and mechanical parameters align, provided the application requirements accommodate the performance difference.

Engineering Selection Recommendations

ADS5547IRGZR is classified as a direct manufacturer substitute. This part maintains full electrical and mechanical compatibility with the ADS5545IRGZRG4 while offering an increased sampling rate of 210M compared to 170M. The ADS5547IRGZR carries active product status, ensuring ongoing manufacturer support and supply availability. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly processes.

ADS5545IRGZT is classified as a parametric equivalent. This part provides identical electrical performance to the ADS5545IRGZRG4, maintaining the 170M sampling rate and all other core specifications. The ADS5545IRGZT carries active product status and is available in higher inventory quantities (1504 Pcs). This part is ROHS3 compliant and REACH unaffected. Packaging is supplied as Tape & Reel (TR).

Both substitute parts are suitable for applications requiring the ADS5545IRGZRG4 specification. Selection between substitutes depends on sampling rate requirements and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can the ADS5547IRGZR replace the ADS5545IRGZRG4 in existing designs?

A: Yes. The ADS5547IRGZR maintains full pin compatibility, identical package dimensions (48-VQFN 7x7), and equivalent electrical characteristics. The increased sampling rate of 210M versus 170M does not create incompatibility; applications designed for 170M operation function correctly with the higher-performance part.

Q: What is the difference between ADS5547IRGZR and ADS5545IRGZT?

A: The ADS5547IRGZR operates at 210M sampling rate, while the ADS5545IRGZT operates at 170M sampling rate, matching the original ADS5545IRGZRG4 specification. Both parts are electrically and mechanically compatible. Selection depends on whether the application requires the higher sampling rate capability.

Q: Are there packaging differences between the main part and substitutes?

A: The ADS5545IRGZRG4 is supplied in standard packaging format. Both substitute parts (ADS5547IRGZR and ADS5545IRGZT) are supplied as Tape & Reel (TR), which is standard for high-volume production. All three parts use identical 48-VQFN (7x7) package geometry and are surface-mount compatible.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both ADS5547IRGZR and ADS5545IRGZT are ROHS3 compliant and REACH unaffected, matching the compliance profile of the ADS5545IRGZRG4. Moisture sensitivity level is identical at MSL 3 (168 Hours) for all parts.

Q: Why is the ADS5545IRGZRG4 marked as obsolete?

A: Product obsolescence is determined by the manufacturer. Active alternatives (ADS5547IRGZR and ADS5545IRGZT) provide equivalent or enhanced functionality and are recommended for new designs and production continuity.
