VREFHI Input Requirements The DAC8420 utilizes a unique, patented DAC switch driver circuit which compensates for different supply, reference volt- age, and digital code inputs. This ensures that all DAC ladder switches are always biased equally, ensuring excellent linearity under ...

DAC8420 single supply operation is obtained with the output load connected to ground, so the output stage does not have to sink current. Like all amplifiers, the DAC8420 output buffers do generate voltage noise, 52 nV/ Hz typically. This is ...
