DAC38RF83IAAVR

Digital To Analog Converters Overview

The DAC38RF83IAAVR is a dual-channel, 14-bit digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sampling rate of 9 GSPS and features 6x to 24x interpolation capabilities. The device integrates a 6 GHz and 9 GHz phase-locked loop (PLL) for clock synthesis. It utilizes a current-steering architecture with buffered voltage outputs, operating within an analog supply range of 1 V to 1.8 V and a digital supply of 1 V. The component is housed in a 144-FCBGA package and functions across a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates high-frequency PLL synthesizers supporting 6 GHz and 9 GHz operation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging versus the standard tray configuration found in datasheets. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these details are subject to change and vary by region.

Digital To Analog Converters Selection Notes

Select this component when high-speed multi-carrier signal generation is required. Ensure the system design accommodates the 144-FCBGA thermal requirements and provides stable power rails for the integrated PLL. Verify that the host processor supports the JESD204B interface protocol required for data transmission.

Digital To Analog Converters Part Context

This part belongs to the DAC38RF83 family, designed for high-performance RF applications. It shares architectural similarities with other members like the DAC38RF87 but differs in specific frequency ranges and performance metrics. The IAAV suffix denotes the industrial temperature grade and specific package variant.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC38RF87IAAVR for higher frequency requirements or the DAC38RF82IAAVR for lower speed applications. Verify pin compatibility and register settings before swapping, as internal architectures may differ slightly between family members.
