Digital To Analog Converters Procurement Notes

Verify the specific suffix IZAY corresponds to the nFBGA-196 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure compatibility with required operating voltage levels and interface standards for the target system design.

Digital To Analog Converters Selection Notes

Select this component for designs requiring dual-channel 16-bit resolution at high sampling frequencies. Consider the 196-NFBGA package constraints for PCB layout. Evaluate thermal management needs given the 800 mW power dissipation. Compare against other family members like DAC3482IRKDT if WQFN-88 packaging is preferred for space-constrained applications.

Digital To Analog Converters Part Context

This part belongs to the DAC3482 series of high-performance data converters. It shares core specifications with variants such as DAC3482IRKDT but differs in packaging and reel/tray configuration. The series is designed for demanding RF and microwave applications requiring precise signal generation.

Digital To Analog Converters Replacement Considerations

The DAC3482IRKDT serves as a functional alternative within the same series, offering identical electrical performance but utilizing a WQFN-88 package instead of the NFBGA-196. Verify pinout and footprint compatibility before substitution.

Digital To Analog Converters FAQ

How is the total delay from input to output calculated?

Total delay is determined by adding the digital delay, which depends on the FIFO usage and interface width, to the fixed analog delay specified in the datasheet.

What is the differential nonlinearity (DNL) specification?

The DAC3482IZAY has a typical DNL specification of +/- 2 LSB.

Does the device support internal reference voltages?

Yes, the device includes an internal reference voltage of 1.2 V, though external references can also be utilized depending on the application requirements.
