DAC38RF85IAAVR

Digital To Analog Converters Overview

The DAC38RF85IAAVR is a single-channel, 14-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It supports an ultra-high-speed sample rate of 9 GSPS and incorporates 6x to 24x interpolation capabilities. The device features a built-in 6 GHz and 9 GHz phase-locked loop (PLL) for clocking flexibility. It utilizes the JESD204B interface for data input and operates within a temperature range of -40°C to +85°C. The component is housed in a 144-pin FCBGA package and consumes approximately 2.195 W of power under typical operating conditions.

Digital To Analog Converters Feature Summary

• Integrates high-speed interpolation filters ranging from 6x to 24x to reduce host processor data rates.
• Includes an on-chip PLL capable of generating internal clocks at 6 GHz and 9 GHz frequencies.
• Supports standard JESD204B serial interface protocols for high-speed digital data transfer.

Digital To Analog Converters Applications

• Wireless base station transmitter systems
• Software-defined radio platforms
• Direct RF synthesis applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration distinct from tray versions. Confirm the IAAV variant specifications match the required thermal and electrical parameters for the target design environment before finalizing orders.

Digital To Analog Converters Selection Notes

Select this model when a single-channel output is sufficient for the application architecture. Compare against dual-channel alternatives like the DAC38RF83 if simultaneous independent signal generation is required. Ensure the system supports the necessary JESD204B lane configurations for the chosen interpolation factor.

Digital To Analog Converters Part Context

This component belongs to the DAC38RF8x family of high-performance RF DACs designed for demanding communication infrastructure. It shares core architectural similarities with other members of the series but differs in channel count and specific pinout configurations suitable for single-ended or differential output implementations.

Digital To Analog Converters Replacement Considerations

The DAC38RF85IAAV serves as the non-reel equivalent part number for board-level prototyping. Verify compatibility with existing PCB footprints and reflow profiles when transitioning between reel and tray packaging formats.
