Welcome to the Analog Devices Five Things to Know About DACs Part 4: Buffering product training module. So far in this series, resolution and accuracy, total unadjusted error, and output noise have been covered. This module will now take a look at the buffering of the DAC. It is split into two sections: buffering of the reference input pin, and buffering of the output. Both sections will discuss some of the technologies that require buffering as well as some instances where buffering is not necessary. Additionally, some tips on selecting buffers will be presented at the end of this module.
