DAC38RF80IAAV

Digital To Analog Converters Overview

The DAC38RF80IAAV is a dual-channel, 14-bit RF-sampling digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sampling rate of 9 GSPS and features an integrated JESD204B interface for high-speed data transmission. The device includes an on-chip phase-locked loop (PLL) capable of operating at 6 GHz and 9 GHz frequencies, with interpolation factors ranging from 6x to 24x. It offers flexible output configurations, supporting both single-ended and differential voltage outputs. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 144-FCBGA package.

Digital To Analog Converters Procurement Notes

Verify the specific revision level against the manufacturer's latest datasheet to ensure compatibility with current design requirements. Confirm that the ordering suffix matches the desired package variant and quality grade. Cross-reference the part number with official distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when designing systems requiring high linearity and wide instantaneous bandwidth at RF frequencies. Evaluate the power consumption profile against thermal management capabilities, as high sampling rates increase dissipation. Ensure the host system supports the required JESD204B lane count and clocking architecture to fully utilize the device's interpolation features.

Digital To Analog Converters Part Context

This device belongs to the DAC38RF family of RF-sampling converters designed for demanding wireless infrastructure applications. It complements lower-speed DACs by providing direct upconversion capabilities, reducing system complexity and bill-of-materials costs in multi-carrier transmitter designs.

Digital To Analog Converters Replacement Considerations

The DAC38RF80IAAVR serves as the reel-based alternative to the tray-packaged IAAV version. Other members of the DAC38RF series may offer different channel counts or performance trade-offs but require careful interface verification.
