DAC715PLG4 Equivalent & Substitute Parts

Part Overview

The DAC715PLG4 is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output buffering. This component features an R-2R architecture with internal reference and parallel data interface, operating across a supply voltage range of ±11.4V to ±16.5V.

The DAC715PLG4 is classified as obsolete. Identifying suitable substitute components is necessary to support ongoing system maintenance, design updates, and procurement continuity where original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC715PLG4 is determined by the following critical parameters that must remain constant:

• 16-bit resolution and single D/A converter configuration
• 10µs settling time performance
• Voltage-buffered output type with parallel data interface
• Internal reference architecture with R-2R topology
• ±11.4V to ±16.5V analog supply voltage compatibility
• ±2 LSB INL and ±1 LSB DNL specifications
• 0°C to 70°C operating temperature range

The DAC715UL qualifies as a direct functional equivalent, maintaining identical electrical specifications while differing only in package format and mounting technology. Both components share the same base product number (DAC715) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The DAC715UL is the manufacturer-recommended substitute for the DAC715PLG4. Both components maintain identical electrical performance specifications and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The primary distinction between these components is packaging and mounting technology. The DAC715PLG4 uses through-hole DIP packaging, while the DAC715UL employs surface-mount SOIC packaging. This difference requires PCB redesign if direct board-level substitution is intended.

The DAC715UL carries active product status from Texas Instruments, ensuring ongoing availability and supply chain support. The DAC715PLG4, classified as obsolete, presents long-term procurement risk.

Selection between these components should be based on:

• PCB assembly capability and design constraints (through-hole versus surface-mount)
• Supply chain requirements and inventory planning
• Manufacturing process compatibility with existing production workflows

Frequently Asked Questions (FAQ)

Q: Can the DAC715UL be used as a direct replacement for the DAC715PLG4 without circuit modification?

A: Electrical substitution is valid. The DAC715UL maintains identical functional specifications, supply voltage requirements, and performance characteristics. However, physical substitution requires PCB redesign due to different package formats (28-DIP versus 28-SOIC) and mounting technologies (through-hole versus surface-mount).

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is determined by matching resolution (16-bit), settling time (10µs), output type (voltage-buffered), data interface (parallel), reference architecture (internal R-2R), supply voltage range (±11.4V to ±16.5V), and linearity specifications (±2 LSB INL, ±1 LSB DNL).

Q: Does the DAC715UL meet the same regulatory compliance requirements?

A: Yes. Both the DAC715PLG4 and DAC715UL are ROHS3 Compliant and REACH Unaffected, maintaining equivalent environmental and regulatory status.

Q: Why is the DAC715PLG4 classified as obsolete?

A: Product obsolescence reflects Texas Instruments' discontinuation of the through-hole DIP package variant. The DAC715 architecture continues in active production through surface-mount packaging options such as the DAC715UL.

Q: Are there any performance differences between the two components?

A: No. Both components share identical electrical specifications, including resolution, settling time, output buffering, supply voltage range, and linearity performance. Differences are limited to package format and mounting technology.
