DAC5689IRGCT

Digital To Analog Converters Overview

The DAC5689IRGCT is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It operates at a sampling rate of 800 MSPS and features an interpolating architecture supporting 2x to 8x interpolation factors. The device utilizes a current sink architecture with differential outputs and settles in 10.4ns typical time. It requires analog supply voltages between 3V and 3.6V and digital supplies between 1.7V and 1.9V. Non-linearity specifications include ±4 LSB INL and ±2 LSB DNL. It is housed in a 64-VQFN (9x9) package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature range compatibility. Ensure that the ordering information matches the required interpolation settings and power supply configurations for the target application environment. Cross-reference the component marking with official documentation to prevent counterfeit substitution.

Digital To Analog Converters Selection Notes

Select this component when high-speed dual-channel conversion with precise 16-bit resolution is required. The integrated interpolation reduces host processor load compared to non-interpolating alternatives. Consider the differential output requirement and supply voltage constraints during circuit design. Evaluate thermal performance within the 64-VQFN package for dense PCB layouts.

Digital To Analog Converters Part Context

This part belongs to the DAC568x family of high-speed digital-to-analog converters from Texas Instruments. It shares architectural similarities with the DAC5688 but offers higher speed and interpolation capabilities. The IRGCT designation indicates the industrial temperature range and VQFN packaging variant used for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

The DAC5688IRGCT is a related component within the same product family. Verify pinout compatibility and functional differences regarding interpolation support before substitution. Check datasheet specifications for settling time and linearity metrics to ensure performance alignment.
