DAC7715UB/1K

Digital To Analog Converters Overview

The DAC7715UB/1K is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with four independent converters housed in a 16-SOIC package. The device operates within a supply voltage range of 14.25 V to 15.75 V for both analog and digital domains. Key electrical specifications include a settling time of 10 µs, a sampling rate of 89 kS/s, and a gain error of 0.05% FSR. Non-linearity performance is specified at ±1 LSB for both integral (INL) and differential (DNL) errors. The component supports an operating temperature range from -40°C to +85°C and includes a reset-to-mid-scale feature.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging details. The /1K suffix typically indicates reel packaging, whereas standard versions may use tubes. Ensure compatibility with existing board layouts regarding the SOIC-16 footprint and thermal requirements. Confirm RoHS compliance status through official datasheets before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized 12-bit voltage outputs with high precision. The 10 µs settling time and low gain error make it suitable for applications demanding accurate analog signal reproduction. Consider the serial interface constraints if system timing is critical. Verify that the required supply voltage aligns with the specified 14.25 V to 15.75 V range for optimal performance.

Digital To Analog Converters Part Context

This part belongs to the DAC7715 series, which focuses on precision multi-channel conversion. It shares architectural similarities with the DAC7714 but offers distinct channel configurations or performance optimizations. The device is designed for industrial environments where reliability and accuracy are paramount. It serves as a specialized solution for complex analog output requirements in embedded systems.

Digital To Analog Converters Replacement Considerations

The DAC7715UBG4 is listed as a parameter-equivalent alternative. Verify pinout compatibility and electrical specifications before substitution. Other family members like the DAC7714UB may offer similar functionality but require validation of specific performance metrics such as non-linearity and settling time.
