DAC715PL Equivalent & Substitute Parts

Part Overview

The DAC715PL 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 DAC715PL is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC715PL is determined by strict equivalence across the following critical parameters:

• Resolution: 16-bit conversion capability
• Converter Count: Single D/A converter per package
• Settling Time: 10µs maximum
• Output Configuration: Voltage output with buffering
• Data Interface: Parallel input
• Reference: Internal reference type
• Supply Voltage Range: ±11.4V to ±16.5V analog supply
• Linearity: ±2 LSB INL and ±1 LSB DNL specifications
• Architecture: R-2R resistor ladder topology
• Temperature Range: 0°C to 70°C operation

The DAC715UL qualifies as a direct functional equivalent, maintaining identical electrical specifications while differing only in package form factor 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 serves as the active-status equivalent for the obsolete DAC715PL. Both components maintain identical electrical performance specifications, including 16-bit resolution, 10µs settling time, R-2R architecture, and ±2/±1 LSB linearity characteristics. The primary distinction lies in packaging and mounting technology: the DAC715PL uses through-hole 28-DIP configuration, while the DAC715UL employs surface-mount 28-SOIC technology.

Selection between these components depends on board-level assembly requirements. Through-hole mounting (DAC715PL) is suitable for legacy systems or applications requiring manual rework capability. Surface-mount technology (DAC715UL) is appropriate for modern manufacturing processes and high-density PCB layouts. Both components maintain ROHS3 compliance and are manufactured by Texas Instruments, ensuring consistent quality and long-term availability for the active part.

The DAC715UL's active product status provides superior long-term supply chain reliability compared to the obsolete DAC715PL.

Frequently Asked Questions (FAQ)

Q: Can the DAC715UL directly replace the DAC715PL in existing designs?

A: Electrical substitution is complete. The DAC715UL maintains identical functional specifications. Physical substitution requires PCB redesign to accommodate the 28-SOIC surface-mount package in place of the 28-DIP through-hole configuration.

Q: What are the key differences between these components?

A: The DAC715PL and DAC715UL differ only in package form factor and mounting technology. All electrical parameters, including resolution, settling time, linearity, supply voltage range, and operating temperature, are identical.

Q: Is the DAC715UL suitable for new designs?

A: Yes. The DAC715UL is classified as active product status, making it the recommended choice for new applications requiring 16-bit parallel-interface digital-to-analog conversion with internal reference and buffered voltage output.

Q: What is the impact of the different Moisture Sensitivity Levels (MSL)?

A: The DAC715PL carries MSL 1 (unlimited shelf life), while the DAC715UL carries MSL 3 (168-hour floor life after moisture exposure). This affects storage and handling procedures for the surface-mount component but does not impact electrical performance or functional compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both the DAC715PL and DAC715UL are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
