DAC7714U/1K

Digital To Analog Converters Overview

The DAC7714U/1K is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and delivers buffered voltage outputs. The device operates with dual analog power supplies ranging from 14.25 V to 15.75 V and a digital supply of 5 V. Key electrical specifications include a settling time of 10 µs, a sampling rate of 89 kS/s, and a maximum power consumption of 45 mW. Linearity performance is characterized by a differential nonlinearity (DNL) and integral nonlinearity (INL) of ±1 LSB, with a gain error of 0.05% FSR. It utilizes a serial interface for data input and is housed in a 16-pin SOIC package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 12-bit DAC channels within a single integrated circuit.
• Integrated reset function that forces all output channels to mid-scale upon initialization or specific control signals.
• High precision linearity with ±1 LSB DNL and INL specifications ensuring accurate signal reproduction.
• Low power consumption design suitable for battery-operated or thermally constrained industrial applications.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog signal generation.
• Programmable logic controller (PLC) analog output modules.
• Data acquisition systems utilizing serial communication interfaces.
• Test and measurement equipment requiring precise voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'U/1K' against the manufacturer's current datasheet to confirm packaging details, as suffixes often denote tube versus reel quantities. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 12-bit resolution is required with a serial interface. Compare against the DAC7715 series if higher accuracy or different pinout configurations are needed. Verify that the 10 µs settling time meets the system's update rate requirements. Ensure the SOIC-16 package footprint aligns with the PCB layout constraints.

Digital To Analog Converters Part Context

The DAC7714 belongs to the DAC771x family of precision digital-to-analog converters from Texas Instruments. This family shares common architectural features such as the R-2R ladder structure and serial interface protocols. The DAC7714 specifically offers a quad-channel configuration, distinguishing it from single-channel variants like the DAC7731 or other members of the broader DAC77xx series.

Digital To Analog Converters Replacement Considerations

The DAC7715UB is documented as a parameter-equivalent alternative. Verify pinout compatibility and specific electrical tolerances between the DAC7714 and DAC7715 models before substitution. Check for any differences in packaging options or lead times between the original part and the equivalent.
