DAC7545GLUR Equivalent & Substitute Parts

Part Overview

The DAC7545GLUR is a 12-bit digital-to-analog converter manufactured by Texas Instruments, housed in a 20-SOIC surface mount package. This component features an R-2R architecture with external reference capability and unbuffered current output, designed for parallel data interface applications requiring 12-bit resolution.

The DAC7545GLUR is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, system maintenance, and design continuity where this component is specified in existing applications.

Critical Matching Parameters:

• Resolution: 12 bits
• Number of converters: 1
• Output configuration: Current - Unbuffered
• Data interface: Parallel
• Reference type: External
• Supply voltage ranges: Analog 5V ~ 15V, Digital 5V ~ 15V
• INL/DNL specifications: ±0.5 (Max), ±1 (Max)
• Architecture: R-2R
• Operating temperature range: -40°C ~ 85°C
• Package type: 20-SOIC
• Mounting type: Surface Mount

The substitute parts MX7545AKEWP+ and MX7545AKEWP+T meet all critical electrical parameters and package requirements. Both are manufactured by Analog Devices Inc./Maxim Integrated and maintain functional equivalence with the original DAC7545GLUR specification.

Parameter Comparison

Engineering Selection Recommendations

Both MX7545AKEWP+ and MX7545AKEWP+T are active, production-supported alternatives to the obsolete DAC7545GLUR. Selection between these two substitute parts depends on packaging and inventory requirements:

MX7545AKEWP+ is supplied in tube packaging and maintains 784 units in current inventory stock.

MX7545AKEWP+T is supplied in tape and reel format and maintains 3200 units in current inventory stock. This packaging format is standard for automated assembly processes and offers higher volume availability.

Both substitute parts demonstrate improved moisture sensitivity characteristics (MSL 1 versus MSL 3) and faster settling time (1µs versus 2µs), providing enhanced reliability and performance margins compared to the original DAC7545GLUR specification. All regulatory compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained across both substitute options.

Frequently Asked Questions (FAQ)

Q: Can MX7545AKEWP+ and MX7545AKEWP+T be used interchangeably with DAC7545GLUR?

A: Yes. Both substitute parts meet all critical electrical specifications and package requirements. The primary difference is packaging format: tube versus tape and reel. Functional performance and pin compatibility are identical.

Q: What is the difference between MX7545AKEWP+ and MX7545AKEWP+T?

A: Both parts are electrically identical. MX7545AKEWP+ uses tube packaging; MX7545AKEWP+T uses tape and reel packaging. Tape and reel format is optimized for automated assembly processes. Selection depends on assembly method and volume requirements.

Q: Are there any performance differences between the DAC7545GLUR and the substitute parts?

A: The substitute parts offer improved settling time (1µs versus 2µs) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3). These represent performance enhancements over the original specification.

Q: What is the 20-SOIC package specification?

A: 20-SOIC refers to a 20-pin Small Outline Integrated Circuit package with 0.295 inches (7.50mm) width. This is a surface mount package type compatible with standard PCB assembly equipment.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both MX7545AKEWP+ and MX7545AKEWP+T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does MSL 1 (Unlimited) mean compared to MSL 3 (168 Hours)?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. MSL 1 (Unlimited) allows indefinite storage without special moisture control. MSL 3 (168 Hours) requires moisture control measures and limits storage duration to 168 hours after opening the moisture barrier bag.
