DAC38RF89IAAVR

Digital To Analog Converters Overview

The DAC38RF89IAAVR is a dual-channel, 14-bit digital-to-analog converter designed for high-speed radio frequency applications. It operates at a sample rate of 9 GSPS and supports interpolation factors ranging from 6x to 24x. The device integrates a phase-locked loop (PLL) capable of locking to 6 GHz or 9 GHz reference frequencies. It utilizes a JESD204B interface for data input and is housed in a 144-pin FCBGA package. The component functions within an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IAAVR' against official Texas Instruments documentation to confirm pinout compatibility and thermal characteristics. Ensure that the ordering information matches the exact package type and moisture sensitivity level required for the manufacturing process. Cross-reference the date code and lot traceability if long-term supply stability is a critical project requirement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel architecture with 14-bit resolution and 9 GSPS throughput is required. The integrated PLL and interpolation features reduce external clock distribution complexity. Compare power consumption and SFDR specifications against alternative devices in the DAC38RF family to ensure alignment with system noise floor and linearity constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC38RF family of ultra-high-speed digital-to-analog converters. The family shares common architectural features such as JESD204B interfaces and similar packaging options. Variations within the series typically involve differences in maximum sample rates, interpolation capabilities, and integrated PLL specifications. This specific model represents a mid-range performance option within the high-speed portfolio.

Digital To Analog Converters Replacement Considerations

The DAC38RF87IAAVR and DAC38RF80IAAV are related components within the same product family. Verify pin-to-pin compatibility and electrical parameter overlaps before substitution. Differences in sample rates and interpolation factors must be evaluated to ensure functional equivalence in the target application.
