DAC5689IRGCR

Digital To Analog Converters Overview

The DAC5689IRGCR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It supports an update rate of up to 800 MSPS with a 64-pin VQFN package measuring 9x9 mm. The device integrates 2x to 8x interpolation filters and a 32-bit complex numerically controlled oscillator for frequency mixing. It operates within an industrial temperature range of -40°C to +85°C, utilizing separate analog (3.3V) and digital (1.8V) power supplies.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm pin compatibility and internal configuration differences. Confirm current manufacturing status as product lines may transition or become obsolete. Ensure the supplier provides valid traceability documents matching the manufacturer's specifications.

Digital To Analog Converters Selection Notes

Select this component when dual-channel high-speed conversion is required alongside integrated digital signal processing capabilities. The built-in interpolation filters reduce external processor load. Verify that the system requires the specific 800 MSPS performance and complex mixer features rather than simpler DAC architectures.

Digital To Analog Converters Part Context

This model belongs to the DAC568x family of high-performance digital-to-analog converters designed for demanding communication applications. It serves as a specialized solution for multi-standard radio architectures requiring precise signal generation and low distortion characteristics in compact form factors.

Digital To Analog Converters Replacement Considerations

The DAC5688 is a related variant within the same series. Note that the DAC5688 includes an on-chip clock multiplier PLL, whereas the DAC5689 does not. Verify if the external clocking requirements align with the absence of the PLL in this specific part number.
