DAC38RF90IAAVR

Digital To Analog Converters Overview

The DAC38RF90IAAVR is a dual-channel, 14-bit digital-to-analog converter (DAC) 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) with 6 GHz and 9 GHz VCOs for clock generation. It utilizes a JESD204B interface for data input and employs a current source architecture. Key performance metrics include a typical power consumption of 3800 mW and an SFDR of 72 dB. The component operates within a temperature range of -40°C to 85°C and is housed in a 144-pin FCBGA package.

• Test and measurement equipment requiring high-frequency analog output

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AAVR' against official Texas Instruments documentation to confirm package type, tape-and-reel configuration, and environmental rating. Ensure compatibility with required JESD204B lane configurations and clock frequencies during sourcing. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm lead times and availability status directly with the supplier prior to order placement.

Digital To Analog Converters Selection Notes

Select this component when designing systems requiring dual-channel outputs at sampling rates up to 9 GSPS. The integrated interpolation factors reduce the necessary input data rate from the host FPGA or processor. Verify that the system design accommodates the thermal dissipation requirements associated with the typical 3800 mW power consumption. Ensure the PCB layout supports the 144-FCBGA package pitch and impedance matching for the JESD204B interface signals.

Digital To Analog Converters Part Context

This device belongs to the DAC38RF family of ultra-high-speed digital-to-analog converters designed for RF applications. It shares architectural similarities with other members like the DAC38RF83 and DAC38RF93, differing primarily in specific interpolation support and internal PLL configurations. The IAAVR suffix denotes the specific commercial grade temperature range and packaging variant offered by Texas Instruments for mass production.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the DAC38RF93IAAVR and DAC38RF83IAAVR. Verify pin-to-pin compatibility and register-level software compatibility before substitution. Differences in interpolation ratios and PLL VCO ranges between these variants may require schematic or firmware adjustments.
