DAC38J84IAAVR

Digital To Analog Converters Overview

The DAC38J84IAAVR is a quad-channel, 16-bit digital-to-analog converter from Texas Instruments. It supports sampling rates of 1.6 GSPS and 2.5 GSPS with a current source output structure. The device utilizes a parallel interface and operates on 3.3 V analog and 900 mV digital supply voltages. Key performance metrics include a differential nonlinearity (DNL) of +/- 4 LSB, integral nonlinearity (INL) of +/- 6 LSB, and an spurious-free dynamic range (SFDR) of 79 dB. It features a 10 ns settling time and functions within a temperature range of -40°C to +85°C in a 144-lead FCBGA package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AAVR' against the manufacturer's official datasheet to confirm the reel packaging configuration and tape-and-reel specifications. Ensure the component matches the required moisture sensitivity level and reflow soldering profile for surface-mount assembly processes.

Digital To Analog Converters Selection Notes

Select this model when four independent high-speed channels are required for complex modulation schemes. Compare the 1.6/2.5 GSPS speed options against system bandwidth requirements. Verify that the parallel interface compatibility aligns with the available digital processing resources and clock distribution network.

Digital To Analog Converters Part Context

This component belongs to the DAC38J84 family, designed for high-performance RF applications.
