DAC5688IRGCT

Digital To Analog Converters Overview

The DAC5688IRGCT is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes a current-sink architecture and features a parallel LVDS data interface for high-speed operation. The device operates with an analog supply voltage range of 3V to 3.6V and a digital supply voltage range of 1.7V to 1.9V. Key electrical specifications include a typical settling time of 10.4ns, with integral nonlinearity (INL) of ±4 LSB and differential nonlinearity (DNL) of ±2 LSB. It is housed in a 64-VQFN package with an exposed pad, designed for surface-mount installation.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling procedures. Ensure compatibility with the required analog and digital supply voltages during system design. Confirm that the 64-VQFN footprint matches the PCB layout constraints and thermal requirements for the intended operating environment.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance with 16-bit resolution is required alongside high-speed parallel interfaces. Consider the current-sink output nature when designing external termination networks. Verify that the operating temperature range of -40°C to 85°C meets the environmental demands of the target application compared to other available DAC families.

Digital To Analog Converters Part Context

This part belongs to the DAC5688 family of high-speed digital-to-analog converters from Texas Instruments. It shares architectural similarities with related models like the DAC5681 but offers dual channels instead of a single channel. The IRGCT suffix indicates a specific package variant within the broader product line, distinct from older or obsolete versions in the same series.

Digital To Analog Converters Replacement Considerations

Direct substitutes may include other dual-channel 16-bit DACs from the same manufacturer. Check pinout compatibility and electrical specifications against alternatives like the DAC5681 if single-channel operation suffices. Verify that any replacement maintains the required LVDS interface and supply voltage ranges.
