DAC3482IRKD25

Digital To Analog Converters Overview

The DAC3482IRKD25 is a dual-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum sample rate of 1.25 GSPS with very low power consumption of 900 mW at full operating conditions. The device features selectable 2x to 16x interpolation filters and a flexible on-chip complex mixer with a 48-bit NCO. It utilizes an LVDS data bus interface and includes a high-performance PLL for clock multiplication. Characterized for operation between -40°C and +85°C, it is housed in an 88-pin WQFN-MR package measuring 9mm x 9mm.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RKD25' against the manufacturer's current orderable addendum to confirm package type and availability. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the datasheet revision SLAS748F for any updates regarding pin configurations or electrical characteristics before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic range and low power consumption in dual-channel architectures. Consider the 88-pin WQFN-MR package for space-constrained designs. Evaluate the need for internal clock multiplication versus external clocking based on jitter requirements. Verify that the system can support the LVDS interface timing and voltage levels specified in the digital characteristics section.

Digital To Analog Converters Part Context

The DAC3482 series includes variants such as the DAC3482IZAYR, which uses a 196-ball NFBGA package. The RKD suffix specifically denotes the 88-pin WQFN-MR package option. This family is designed for communication systems requiring superior crosstalk performance and high dynamic range. The IRKDT variant shares similar electrical specifications but may differ in packaging or reel configuration.

Digital To Analog Converters Replacement Considerations

The DAC3482IZAYR is a direct functional substitute within the same family, differing primarily in the 196-ball NFBGA package instead of the 88-pin WQFN-MR. Designers must account for footprint changes and thermal pad requirements when switching packages. Other members of the DAC34xx family may offer different channel counts or speeds but require schematic and software verification.
