DAC5672AIPFBG4 Equivalent & Substitute Parts

Part Overview

The DAC5672AIPFBG4 is a 14-bit digital-to-analog converter (DAC) with dual output channels, manufactured by Texas Instruments. This device features current-unbuffered output, parallel data interface, and supports both external and internal reference configurations. The part is discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives that maintain full electrical and mechanical compatibility for seamless design substitution.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC5672AIPFBG4 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Critical Parameters for Substitution:

• 14-bit resolution with dual D/A converter channels
• 20ns typical settling time
• Current-unbuffered output with differential output capability
• Parallel data interface supporting external and internal reference configurations
• 3V to 3.6V supply voltage range for both analog and digital domains
• INL/DNL specifications of ±1.1 and ±0.75 LSB respectively
• Current source architecture
• 48-TQFP (7x7) surface mount package
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and REACH unaffected status

Substitute parts must match all parameters listed above. Packaging format (tray versus tube) does not affect electrical or mechanical compatibility and is therefore not a substitution barrier.

Parameter Comparison

Engineering Selection Recommendations

DAC5672AIPFB is the manufacturer-recommended substitute. This part maintains active product status and is available in higher inventory quantities (1862 pcs), ensuring supply chain continuity. All electrical specifications and mechanical parameters are identical to the DAC5672AIPFBG4. The primary distinction is packaging format (tray versus tube), which does not affect circuit performance or PCB assembly compatibility.

DAC5672IPFB is a parametric equivalent substitute. This part is also active and maintains identical electrical and mechanical specifications. The part number variation reflects internal Texas Instruments product line differentiation but does not indicate functional differences relevant to circuit substitution. Inventory availability is 1697 pcs.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can DAC5672AIPFB and DAC5672IPFB be used interchangeably with DAC5672AIPFBG4?

A: Yes. Both parts are direct electrical and mechanical equivalents. All critical parameters including resolution, settling time, output type, supply voltage, and package configuration are identical. PCB layout and circuit design require no modification.

Q: What is the difference between tray and tube packaging?

A: Packaging format affects only component handling and storage during manufacturing and assembly. Tray packaging is standard for automated pick-and-place assembly. Tube packaging is used for manual handling or lower-volume applications. Electrical performance and PCB mounting are unaffected by packaging format.

Q: Why is the original part discontinued?

A: Product discontinuation at DiGi Electronics reflects inventory management and market demand decisions by the distributor, not product obsolescence. Texas Instruments continues manufacturing equivalent variants (DAC5672AIPFB and DAC5672IPFB) with active product status.

Q: Are there any temperature or compliance differences between the substitutes?

A: No. All three parts operate across the identical temperature range (-40°C to 85°C) and maintain ROHS3 compliance and REACH unaffected status.

Q: Which substitute should be selected for new designs?

A: DAC5672AIPFB is the manufacturer-recommended choice due to active product status and higher inventory availability. DAC5672IPFB is an equivalent alternative if supply constraints exist.
