DAC38RF87IAAVR

Digital To Analog Converters Overview

The DAC38RF87IAAVR is a dual-channel, 14-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It supports a maximum sampling rate of 9 GSPS and features 6x to 24x interpolation capabilities. The device integrates a phase-locked loop (PLL) capable of operating at 6 GHz and 9 GHz frequencies. It utilizes a current-steering architecture with buffered voltage outputs and supports JESD204B data interfaces. The component is housed in a 144-FCBGA package measuring 10 mm x 10 mm. It operates within an ambient temperature range of -40°C to +85°C and requires analog supply voltages between 1.71 V and 1.89 V, alongside digital supply voltages from 0.95 V to 1.05 V.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging rather than tray distribution when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements during storage handling. Ensure the ordering part number matches the exact IAAVR designation to guarantee correct package type and reel quantity specifications.

Digital To Analog Converters Selection Notes

Select this component when dual-channel output with 14-bit resolution at 9 GSPS is required. The integrated interpolation reduces FPGA logic load compared to non-interpolating alternatives. Verify that the 144-FCBGA footprint fits the target PCB layout constraints. Ensure power supply rails match the specified 1.8 V analog and 1.0 V digital requirements.

Digital To Analog Converters Part Context

This device belongs to the DAC38RF8x family, which includes variants like the DAC38RF82, DAC38RF83, and DAC38RF86. These components share similar architectural features but differ in specific performance metrics or feature sets. The DAC38RF87 serves as a high-performance option within this series for demanding RF transmission applications requiring precise signal generation.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package include DAC38RF82IAAV, DAC38RF83IAAV, and DAC38RF86IAAV. Cross-model selection requires verification of specific interpolation ratios and PLL frequency ranges against application requirements.
