DAC38RF97IAAVR

Digital To Analog Converters Overview

The DAC38RF97IAAVR is a dual-channel, 14-bit digital-to-analog converter manufactured by Texas Instruments. It operates at a maximum sample rate of 6.2 GSPS and supports interpolation factors ranging from 12x to 24x. The device features an integrated 6 GHz and 9 GHz phase-locked loop (PLL) for clock generation. It utilizes a current source architecture with voltage output and communicates via the JESD204B interface. Key performance metrics include a typical power consumption of 3.8 W, a settling time of 1 ns, and an SFDR of 72 dB. The component is housed in a 144-FCBGA package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AAVR' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the ordering quantity aligns with the manufacturer's standard packaging requirements. Confirm RoHS compliance status through the latest product change notifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 14-bit resolution and up to 6.2 GSPS throughput is required. Consider the integrated PLL feature if external clock synthesizers are undesirable. Evaluate the 144-FCBGA package constraints during PCB layout planning to ensure adequate thermal dissipation and signal integrity for high-frequency operation.

Digital To Analog Converters Part Context

This part belongs to the DAC38RF97 family, which includes variants such as the DAC38RF90 and DAC38RF83. These devices share similar architectural foundations but differ in maximum sampling rates and interpolation capabilities. The DAC38RF97 specifically targets applications requiring high linearity and speed within the 6 to 9 GHz frequency bands.

Digital To Analog Converters Replacement Considerations

The DAC38RF90IAAVR serves as a higher-speed alternative within the same family, offering 9 GSPS performance. Verify pin-to-pin compatibility and software register settings when substituting between these models to ensure seamless integration into existing designs.
