DAC sampling rate and setting time

 In the slow DAC, the sampling rate is generally not directly marked in the manual, but the setting time is used to explain.

 If you want to use a DAC to output a square wave of 1Msps (it should be said that it is a square wave, the actual output waveform is not standard, unless the SR of the amplifier inside the DAC can reach infinity), then the setting time of the DAC to be used should meet: setting time <1/1Msps=1us;
