Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the nFBGA-196 footprint matches the target PCB design. Check for moisture sensitivity level requirements during storage and handling procedures.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high linearity and low power consumption in dual-channel configurations. Compare against the DAC3482IRKDR if a WQFN-88 package is preferred over the nFBGA-196 form factor. Evaluate system bandwidth requirements against the 1.25 GS/s maximum sampling rate. Consider thermal management needs given the 800 mW power dissipation specification.

Digital To Analog Converters Part Context

This part belongs to the DAC3482 series of ultra-high-speed dual-channel DACs. It is designed to replace older generation converters in high-performance communication systems. The device complements other members like the DAC3484 and DAC34H84 within the same product family, offering distinct package and interface options for varied design constraints.

Digital To Analog Converters Replacement Considerations

The DAC3482IRKDR serves as a pin-compatible alternative with a different package type. Verify electrical specifications remain identical before substitution. Ensure board layout adjustments are made to accommodate the WQFN-88 footprint if switching from the nFBGA-196 package.

Digital To Analog Converters FAQ

How is the total delay calculated for the DAC3482?

Total delay includes analog delay plus digital delay. Digital delay depends on the selected interpolation block, FIFO usage, and interface width (8-bit or 16-bit). Measurement can be performed using the DAC3482EVM with a narrow pulse test pattern.

What is the reference voltage specification?

The device utilizes an external reference voltage of 1.2 V for optimal operation.
