Common performance indicators of DAC

(1) Offset error 
       In DAC, the offset error is defined as the difference between the standard offset point and the actual offset point. In a DAC, the bias point is the step value when the digital input is zero. This error can be corrected by adding peripheral circuits, such as adding a reference voltage. 
(2) Gain error 
       Gain error is manifested in the DAC as the error between the actual output value and the theoretical value when the DAC digital input is at full scale after the offset error is adjusted to zero. Usually this kind of error can also be adjusted by a correction method. 
(3) The resolution 
       is similar to the ADC, and the resolution of the DAC is measured by the minimum analog output that it can distinguish.
(4) The output voltage 
       is understood as the voltage range of the DAC output, and the output voltage range of different types of DACs varies greatly. For voltage output DACs, the general range is 5-10V, and the highest can reach 30V; for current output DACs, the output current is generally around 20mA, and the highest can reach 3A. 
(5) The conversion time 
       refers to the time required for the input digital signal to be converted into an analog output.
