Measured single-ended into 50 Ω 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.
Includes CLOCK pin on SOIC/TSSOP packages and CLK+ pin on LFCSP package in single-ended clock input mode.
Applicable to CLK+ and CLK– inputs when configured for differential or PECL clock input mode.
