DAC5688IRGCR

Digital To Analog Converters Overview

The DAC5688IRGCR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It supports sampling rates up to 800 MSPS and features 2x to 8x interpolation filters. The device operates with an analog supply voltage of 3V to 3.6V and a digital supply voltage of 1.7V to 1.9V. It utilizes a current sink architecture with outputs available in a 64-VQFN (9x9) package with an exposed pad. Integral nonlinearity (INL) is specified at ±4 LSBs, while differential nonlinearity (DNL) is ±2 LSBs. The typical settling time is 10.4ns, and the operating temperature range extends from -40°C to 85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix IRGCR against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and industrial temperature grade. Ensure compatibility with the required 64-VQFN footprint during PCB layout. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution. Confirm that the analog and digital supply voltages match the system power rails before integration.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance at 800 MSPS is required with integrated interpolation capabilities. Compare INL and DNL specifications against system accuracy requirements. Evaluate the 64-VQFN package constraints for thermal management and board space. Verify interface compatibility with the host processor or FPGA driving the digital inputs.

Digital To Analog Converters Part Context

This part belongs to the DAC5688 family of high-speed dual-channel converters. It shares architectural similarities with the DAC5687 and DAC5689 but differs in maximum sampling speed and specific feature sets. The IRGCR designation indicates the specific package type and temperature range within the broader product line.

Digital To Analog Converters Replacement Considerations

Direct substitutes include DAC5688IRGC25 and DAC5688IRGCT. Verify pinout and electrical parameter equivalence before replacement. Consider the DAC5687 if lower sampling rates are acceptable.
