DAC7643VFBR

Digital To Analog Converters Overview

The DAC7643VFBR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an internal reference voltage and operates with a single supply voltage ranging from 2.7V to 5.5V. The device utilizes a serial interface compatible with standard SPI protocols for data input. It provides two independent analog voltage outputs, each capable of driving high-impedance loads. The component is housed in a VSSOP package with eight pins, designed for space-constrained applications requiring precise analog signal generation.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'VFBR' corresponds to the VSSOP-8 package and tape-and-reel packaging configuration. Confirm the operating temperature range matches the industrial grade specifications required for the target environment. Ensure compatibility with the system's serial clock speeds and logic levels before integration.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required without external reference dependencies. Compare against single-channel alternatives if only one output is needed to optimize board space. Consider the serial interface speed requirements relative to the application's update rate needs. Verify power supply constraints align with the specified 2.7V to 5.5V operational range.

Digital To Analog Converters Part Context

This part belongs to the DAC764x family of 16-bit digital-to-analog converters from Texas Instruments. The family includes variants like the DAC7641 and DAC7642, differing primarily in channel count and package options. The VFBR suffix indicates a specific tape-and-reel packaging variant suitable for automated surface-mount assembly processes.
