DAC3484IZAY

Digital To Analog Converters Overview

The DAC3484IZAY is a quad-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum sampling rate of 1.25 GSPS with a typical settling time of 10 ns. The device operates on a 3.3 V analog supply and a 1.2 V digital supply, functioning within an industrial temperature range of -40°C to +85°C. It features current output architecture with differential outputs and utilizes a parallel LVDS interface. The component is housed in a 196-pin nFBGA package.

Digital To Analog Converters Feature Summary

• Integrates digital interpolation filters ranging from 2x to 16x to simplify complex transmit architectures.
• Includes integrated numerically controlled oscillators (NCOs) for frequency translation and signal processing.
• Provides high dynamic performance with specified SFDR and low nonlinearity metrics.

Digital To Analog Converters Applications

• Wideband transmit-receive digital signal processors
• Base station transmitter systems
• Radar signal generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IZAY' against the manufacturer's official datasheet to confirm the package type and commercial/industrial temperature grade. Ensure compatibility with the required PCB footprint for the 196-pin nFBGA configuration. Check for moisture sensitivity level requirements during storage and handling.

Digital To Analog Converters Selection Notes

Select this component when four independent high-speed channels are required at 1.25 GSPS. Compare against the dual-channel DAC3482 if fewer channels suffice. Consider the DAC34H84 if higher input bus speeds or different packaging options are needed while maintaining similar performance characteristics.

Digital To Analog Converters Part Context

This part belongs to the DAC348x family of high-performance data converters designed for demanding RF applications. It shares core architectural similarities with the DAC3482 and DAC34H84, differing primarily in channel count and specific interface configurations. The IZAY suffix denotes a specific commercial-grade variant within this product line.

Digital To Analog Converters Replacement Considerations

The DAC3482 offers a dual-channel alternative with identical speed and resolution. The DAC34H84 provides the same quad-channel performance but may differ in pinout or input interface requirements. Verify mechanical and electrical compatibility before substitution.
