DAC3482IRKDT

Digital To Analog Converters Overview

The DAC3482IRKDT is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sampling rate of 1.25 GSps and features a parallel LVDS interface. The device utilizes a current source architecture with unbuffered current outputs. It operates on a 3.3 V analog supply and a 1.2 V digital supply. Key performance metrics include a settling time of 10 ns, differential nonlinearity (DNL) of ±2 LSB, and integral nonlinearity (INL) of ±4 LSB. The component is housed in an 88-pin WQFN package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates digital interpolation filters ranging from 2x to 16x to simplify complex transmitter architectures.
• Provides ultra-high-speed conversion capabilities suitable for demanding signal processing applications.
• Features low power consumption characteristics relative to its high-speed performance class.

Digital To Analog Converters Applications

• Software-defined radio systems
• Test and measurement equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix IRKDT to confirm the WQFN-88 package type and industrial temperature rating. Ensure compatibility with the required parallel LVDS interface configuration. Check for moisture sensitivity level requirements during storage and handling. Confirm that the reel or cut tape packaging meets assembly line specifications. Validate that the 3.3V and 1.2V power supply rails align with the system design constraints.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 16-bit resolution and 1.25 GSps throughput is required. Consider the WQFN-88 package if board space is limited compared to the BGA alternative. Evaluate the internal interpolation filters if reducing host processor load is a priority. Compare power dissipation figures against thermal management capabilities. Verify interface compatibility with the digital source driving the parallel data lines.

Digital To Analog Converters Part Context

This part belongs to the DAC3482 family of high-performance dual-channel DACs from Texas Instruments. It shares core architectural features with variants like the DAC3482IZAYR, differing primarily in package style and pinout. The family is designed for applications requiring high dynamic range and low power consumption. Other family members may offer different I/O interfaces or channel counts, such as the quad-channel DAC3484.

Digital To Analog Converters Replacement Considerations

The DAC3482IZAYR serves as a package-compatible alternative using a 196-NFBGA footprint. Direct pin-for-pin replacement is not possible due to the distinct WQFN-88 versus NFBGA-196 form factors. System redesign is necessary if switching between these package types. Verify that the electrical parameters remain identical for functional equivalence.
