DAC5682ZIRGC Equivalent & Substitute Parts

Part Overview

The DAC5682ZIRGC is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for high-speed data acquisition applications. This dual-channel DAC features current-unbuffered output with LVDS parallel data interface and supports both external and internal reference configurations. The component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when packaging or tape format differs while maintaining identical electrical and mechanical specifications, enabling flexible procurement and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC5682ZIRGC are identified based on matching all critical electrical and mechanical parameters while differing only in packaging format or tape configuration. The substitution logic is based on the following key parameters that must remain identical:

• 16-bit resolution with dual D/A converters
• 10.4ns typical settling time
• Current-unbuffered output with differential capability
• LVDS parallel data interface
• External and internal reference support
• 3V ~ 3.6V analog supply and 1.7V ~ 1.9V digital supply
• ±4 LSB INL and ±2 LSB DNL specifications
• Current sink architecture
• -40°C ~ 85°C operating temperature range
• 64-VQFN (9x9) package footprint
• Surface mount configuration
• RoHS3 compliance and REACH unaffected status

Variations in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical performance or PCB integration and are therefore considered equivalent for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—DAC5682ZIRGC, DAC5682ZIRGCR, and DAC5682ZIRGCT—are classified as Active product status and maintain identical electrical specifications and compliance certifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance criteria.

DAC5682ZIRGC and DAC5682ZIRGCR are both supplied in Tape & Reel format, with DAC5682ZIRGCR offering higher inventory availability (18,581 units versus 1,417 units). DAC5682ZIRGCT is supplied in Cut Tape & Digi-Reel format with 3,472 units in stock, suitable for applications requiring smaller order quantities or alternative tape configurations.

All parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. Moisture sensitivity level 3 (168 hours) applies uniformly across all variants.

Frequently Asked Questions (FAQ)

Q: Can DAC5682ZIRGCR be used as a direct replacement for DAC5682ZIRGC?

A: Yes. Both parts are electrically and mechanically identical, differing only in packaging format. The difference between Tape & Reel variants does not affect PCB integration, electrical performance, or functional compatibility.

Q: What is the difference between DAC5682ZIRGCT and the other variants?

A: DAC5682ZIRGCT uses Cut Tape & Digi-Reel packaging instead of standard Tape & Reel format. All electrical specifications, pin configurations, and performance characteristics remain identical. The packaging difference accommodates different procurement workflows and order quantities.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All variants operate across -40°C to 85°C, maintaining identical performance specifications throughout this range.

Q: Do packaging differences affect PCB layout or soldering requirements?

A: No. All three parts use the same 64-VQFN (9x9) package footprint with exposed pad. PCB layout, solder pad design, and reflow profiles are identical across all variants.

Q: Which part should be selected for high-volume production?

A: DAC5682ZIRGCR offers the highest inventory availability and is suitable for high-volume applications. DAC5682ZIRGC and DAC5682ZIRGCT are appropriate for standard and lower-volume requirements respectively.

Q: Are all parts RoHS3 compliant?

A: Yes. All three variants are RoHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial applications.
