DAC716UK Equivalent & Substitute Parts

Part Overview

The DAC716UK is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring voltage output buffering. This active product operates across a supply voltage range of ±11.4V to 16.5V and features an SPI data interface with internal reference capability. The DAC716UK is packaged in a 16-SOIC surface mount configuration with 1276 units currently in stock. Substitute parts are identified when equivalent electrical performance and functional specifications are required but alternative packaging or mounting technologies are preferred for system integration.

Substitute Part Grouping Explanation

The DAC716PK qualifies as a direct substitute for the DAC716UK based on identical electrical and functional specifications. Both parts share the same core architecture (R-2R), resolution (16-bit), settling time (10µs), output buffering configuration, SPI interface, and internal reference design. The supply voltage range (±11.4V ~ 16.5V), linearity specifications (±2 LSB INL/DNL), and operating temperature range (0°C ~ 70°C) are identical across both variants.

The primary distinction between these parts is packaging and mounting technology. The DAC716UK uses a 16-SOIC surface mount package (0.295" width, 7.50mm), while the DAC716PK uses a 16-DIP through-hole package (0.300" width, 7.62mm). This substitution is valid when system design requirements permit transition from surface mount to through-hole assembly methods.

Parameter Comparison

Engineering Selection Recommendations

Both the DAC716UK and DAC716PK are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing environments. Selection between these parts depends solely on PCB assembly methodology and mechanical integration requirements.

The DAC716UK is appropriate for applications utilizing surface mount assembly processes and requiring compact board layouts. The DAC716PK is appropriate for applications utilizing through-hole assembly processes or requiring mechanical robustness in high-vibration environments. Electrical performance and functional behavior are equivalent across both variants.
