Measured single-ended into 50 W load.
Output noise is measured with a full-scale output set to 20 mA with no conversion activity. It is a measure of the thermal noise only.
Noise spectral density is the average noise power normalized to a 1 Hz bandwidth, with the DAC converting and producing an output tone.
