ADS5545IRGZR Equivalent & Substitute Parts

Part Overview

The ADS5545IRGZR 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 with a 170 MHz sampling rate and operates from 3V to 3.6V supply voltages. The component is housed in a 48-VQFN (7x7) package with exposed pad for thermal management.

The ADS5545IRGZR carries an obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and system maintenance. Active alternatives with compatible electrical and mechanical specifications are available to ensure uninterrupted component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS5545IRGZR are classified based on strict electrical and mechanical compatibility criteria. The following parameters determine valid substitution:

Critical Parameters for Substitution:

• Resolution: 14 bits
• Number of Inputs: 1 differential input
• Data Interface: LVDS - Parallel, Parallel
• Architecture: Pipelined with S/H-ADC configuration
• Supply Voltage Range: 3V ~ 3.6V (both analog and digital)
• Operating Temperature: -40°C ~ 85°C
• Package: 48-VQFN (7x7) Exposed Pad
• Mounting: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

Sampling Rate Variation: The ADS5545IRGZR operates at 170 MHz. Substitute parts may operate at higher sampling rates while maintaining all other electrical and mechanical specifications. Higher sampling rates do not preclude substitution in applications designed for the original 170 MHz specification.

Parameter Comparison

Engineering Selection Recommendations

ADS5547IRGZR is classified as a direct manufacturer substitute with enhanced performance. This part maintains full electrical and mechanical compatibility with the ADS5545IRGZR while offering an increased sampling rate of 210 MHz. The ADS5547IRGZR carries active product status, ensuring long-term availability and supply chain continuity. This part is supplied in Tape & Reel packaging and holds ROHS3 compliance with REACH unaffected status.

ADS5545IRGZT is classified as a parametric equivalent with identical electrical specifications to the main part. This variant maintains the 170 MHz sampling rate and all other core parameters. The ADS5545IRGZT carries active product status and is supplied in Tape & Reel packaging. This part also maintains ROHS3 compliance and REACH unaffected status, providing a direct functional replacement with improved availability.

Both substitute parts are suitable for applications requiring the ADS5545IRGZR specification. Selection between substitutes depends on packaging requirements (Tape & Reel availability) and sampling rate performance needs.

Frequently Asked Questions (FAQ)

Q: Can the ADS5547IRGZR replace the ADS5545IRGZR in existing designs?

A: Yes. The ADS5547IRGZR maintains identical electrical specifications for resolution, input configuration, data interface, supply voltage, and operating temperature range. The increased sampling rate of 210 MHz does not prevent substitution in applications designed for 170 MHz operation. Pin-to-pin compatibility and package dimensions are identical.

Q: What is the difference between ADS5545IRGZR and ADS5545IRGZT?

A: Both parts share identical electrical specifications and sampling rate (170 MHz). The primary difference is packaging: ADS5545IRGZR is supplied in standard packaging, while ADS5545IRGZT is supplied in Tape & Reel (TR) format. Both maintain the same 48-VQFN (7x7) package footprint and are pin-compatible.

Q: Why is the ADS5545IRGZR marked as obsolete?

A: The ADS5545IRGZR has reached end-of-life status. Active alternatives with equivalent or enhanced specifications are available to support ongoing production and maintenance requirements. The substitute parts listed provide continued access to compatible 14-bit pipelined ADC functionality.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both ADS5547IRGZR and ADS5545IRGZT are ROHS3 compliant and REACH unaffected, matching the compliance status of the original ADS5545IRGZR.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes. All listed parts share identical 48-VQFN (7x7) package dimensions, exposed pad configuration, and surface mount mounting type. PCB footprints and assembly processes remain unchanged across all substitute parts.

Q: What is the moisture sensitivity level for these components?

A: All parts, including the main component and substitutes, carry Moisture Sensitivity Level 3 with a 168-hour floor life rating. Standard moisture control procedures during storage and assembly are required.
