DAC38RF93IAAVR

Digital To Analog Converters Overview

The DAC38RF93IAAVR is a dual-channel, 14-bit digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sample rate of 9 GSPS and features 12x to 24x interpolation capabilities. The device integrates a phase-locked loop (PLL) supporting 6 GHz and 9 GHz operation. It utilizes a current source architecture with JESD204B interface connectivity. Key performance metrics include a differential nonlinearity (DNL) of 0.5 LSB, integral nonlinearity (INL) of 1 LSB, and an SFDR of 72 dB. Power consumption is typically 3.8 W, with a power dissipation of 4.894 W. The component operates within a temperature range of -40°C to +85°C and is housed in a 144-lead FCBGA package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IAAVR' against the manufacturer's official documentation to confirm tape-and-reel packaging status and exact electrical grade. Ensure compatibility with existing PCB footprints for the 144-FCBGA package. Cross-reference lead times and availability directly with authorized distributors or the manufacturer, as supply chain conditions fluctuate. Confirm RoHS compliance and environmental declarations prior to final procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when system requirements demand 14-bit resolution at multi-gigasample rates with integrated interpolation. Compare against the DAC38RF83IAAV if lower interpolation factors are sufficient, or the DAC38RF90IAAVR if different interpolation ratios are needed. Evaluate thermal management solutions due to the 3.8 W typical power consumption. Ensure the host FPGA supports the required JESD204B lane count and SYSREF synchronization protocols for proper integration.

Digital To Analog Converters Part Context

This device belongs to the DAC38RF93 family from Texas Instruments, designed for high-performance RF applications. It shares architectural similarities with other members like the DAC38RF83 but offers distinct interpolation ranges. The IAAV variant denotes a specific commercial temperature grade and package configuration within the broader product line, targeting cost-sensitive yet high-speed wireless infrastructure markets.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives within the same family include the DAC38RF93IAAV (tray packaging). For functional substitutes with different interpolation profiles, consider the DAC38RF83IAAV or DAC38RF90IAAVR. Verify that any replacement maintains the 144-FCBGA footprint and JESD204B interface compatibility.
