DAC3482IRKDR

Digital To Analog Converters Overview

The DAC3482IRKDR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sampling rate of 1.25 GSps with a typical settling time of 10 ns. The device features current source outputs and utilizes a parallel interface for data input. Key performance metrics include a differential nonlinearity (DNL) of ±2 LSB, an integral nonlinearity (INL) of ±4 LSB, and a spurious-free dynamic range (SFDR) of 82 dB. It operates within a temperature range of -40°C to +85°C and is housed in a WQFN-88 package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix IRKDR against the manufacturer's official datasheet to confirm the WQFN-88 package type and industrial temperature range specifications. Ensure that the ordering information matches the required reel quantity and moisture sensitivity level details provided in the latest product documentation before finalizing procurement orders.

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. Compare the WQFN-88 package dimensions against board space constraints. Verify that the parallel interface requirements align with the system's digital logic capabilities and that the current output type suits the downstream analog circuit design without additional buffering.

Digital To Analog Converters Part Context

This part belongs to the DAC3482 series from Texas Instruments, designed for high-performance data conversion tasks. It shares core architectural features with other members of the family but is distinguished by its specific WQFN-88 packaging and industrial temperature rating. The series is targeted at applications demanding high linearity and wide bandwidth in compact form factors.

Digital To Analog Converters Replacement Considerations

The DAC3482IZAYR serves as a functional alternative within the same series, offering identical electrical performance but utilizing a 196-NFBGA package instead of the WQFN-88. Designers must account for significant footprint and pinout differences when considering this substitution.
