DAC7715U/1KG4

Digital To Analog Converters Overview

The DAC7715U/1KG4 is a quad, serial input, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It operates within an extended temperature range of -40°C to +85°C and utilizes an R-2R architecture. The device features a sampling rate of 89 kS/s per channel with a typical settling time of 10 µs. It requires dual power supplies ranging from 14.25 V to 15.75 V for both analog and digital sections. Key performance metrics include a gain error of 0.05% FSR and integral/differential nonlinearity of ±1 LSB. The component is housed in a 16-SOIC package and is supplied in a reel format.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with serial interface control
• Provides buffered voltage outputs suitable for precision applications
• Includes a reset function to initialize outputs to mid-scale

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Precision data acquisition equipment
• Automated test and measurement instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging and compliance status. The /1K suffix indicates tape and reel packaging, which differs from tube packaging found in other variants like the DAC7715UG4. Ensure compatibility with existing board layouts regarding the SOIC-16 footprint and pin configuration before procurement.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with high accuracy and moderate speed is required. Compare against the DAC7714 series if lower resolution or different power supply requirements are acceptable. Verify that the 15 V supply rails match the system design, as this part does not support single low-voltage operation unlike the DAC7615 series.

Digital To Analog Converters Part Context

This part belongs to the DAC7715 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7714 but offers higher resolution. The UG4 suffix denotes lead-free and RoHS-compliant construction. The /1K variant specifically designates the reel packaging option for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7715UB is a parameter-equivalent alternative available in tube packaging. For lead-free versions, the DAC7715UG4 serves as a direct substitute with identical electrical characteristics but different physical packaging.
