DAC716PB Equivalent & Substitute Parts

Part Overview

The DAC716PB 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 internal reference, SPI data interface, and R-2R architecture with ±4 LSB maximum INL/DNL specifications. The DAC716PB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

The DAC716UB qualifies as a direct functional substitute for the DAC716PB based on matching electrical and performance specifications. Both parts share identical core parameters: 16-bit resolution, single D/A converter, buffered voltage output, SPI interface, internal reference, 10µs settling time, ±4 LSB INL/DNL accuracy, R-2R architecture, ±11.4V to ±16.5V analog supply range, and -40°C to 85°C operating temperature. The primary distinction between these parts is packaging format: the DAC716PB uses through-hole 16-DIP (0.300", 7.62mm) mounting, while the DAC716UB employs surface-mount 16-SOIC (0.295", 7.50mm width) technology. Both maintain ROHS3 compliance and identical ECCN/HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

The DAC716UB is the active-status equivalent for the obsolete DAC716PB, with identical electrical performance and specifications. Selection between these parts depends on circuit board design requirements. Through-hole mounting (DAC716PB) is suitable for breadboard prototyping, legacy board designs, and applications requiring manual component replacement. Surface-mount technology (DAC716UB) is appropriate for high-density PCB layouts, automated assembly processes, and modern production environments. Both parts maintain ROHS3 compliance and are unaffected by REACH regulations. The DAC716UB's higher moisture sensitivity level (MSL 3 versus MSL 1) requires controlled storage conditions during manufacturing but does not affect operational performance in sealed applications.

Frequently Asked Questions (FAQ)

Q: Can DAC716UB replace DAC716PB in existing designs? A: Electrical substitution is direct due to identical specifications. Physical substitution requires PCB redesign to accommodate the different package format: 16-DIP through-hole versus 16-SOIC surface-mount.

Q: What is the primary difference between these parts? A: The DAC716PB and DAC716UB are functionally identical 16-bit digital-to-analog converters with matching electrical parameters, settling time, accuracy, and supply requirements. The sole difference is packaging technology: through-hole DIP versus surface-mount SOIC.

Q: Why is DAC716PB listed as obsolete? A: The DAC716PB is classified as obsolete by the manufacturer. The DAC716UB remains in active production and is the recommended part for new designs and ongoing system support.

Q: Are there any compliance differences? A: Both parts are ROHS3 compliant and REACH unaffected. The DAC716UB has MSL 3 (168 hours) moisture sensitivity versus DAC716PB's MSL 1 (unlimited), requiring appropriate storage protocols during manufacturing.

Q: What is the pin-to-pin compatibility? A: These parts are not pin-compatible due to different package formats. Functional equivalence is electrical only; physical board layout changes are required for substitution.

Q: Which part should be selected for new designs? A: The DAC716UB is the appropriate choice for new designs, as it maintains active product status and identical performance specifications while supporting modern surface-mount assembly processes.
