Section 6-5:DAC and ADC Static Transfer Functions and DC Errors The four primary DC errors in a data converter areoffset error, gain error, and two types oflinearity error (differential and integral). Offset and gain errors are analogous to offset and gain errors in amplifiers as ...
can be programmed to 20 bits for Full-Scale, settling to 0.003% within 15ms typical, or 16 bits for Full-Scale, settling to 0.012% within 2ms max. The output range is two times the external reference voltage. On-chip calibration circuitry dramatically reduces low offset and gain errors. ...

Integral Nonlinearity: Integral nonlinearity measures the maximum deviation between the ideal output of a DAC and the actual output after gain and offset errors have been removed. The switches used in series with the R-2R network can affect the INL. Multiplying DACs generally employ NMOS switches...
Total Unadjusted Error (TUE): The offset and gain errors are the biggest contributor to the TUE. The linearity is dominated by the choice of precision DACs. In most cases the linearity error from the DAC is negligible compared to the offset and gain errors. The offset error of the system ...
Other Parts Discussed in Thread: DAC7718 使用DAC7718,VREF值为5V,GAIN值设定为6,OFFSETDAC_CODE值为0,正负15V电源供电,按照下面的公式INPUT_CODE值为2048时输出值为15V, 我现在INPUT_CODE值为256时输出值就是15V
output amplifier The output buffer amplifier is capable of generating near rail-to-rail voltages on its output, which gives an output range of 0 V to AVDD (offset and gain errors affect the absolute VOUT range). It is also capable of driving a load of 2 kΩ in parallel with 1000 pF...
Figure 1 shows how offset and gain errors affect a DAC transfer function for a unipolar voltage DAC. Gain error is a measurement of the span error of the DAC, shown in purple in Figure 1. The gain error is the deviation in slope of the DAC transfer characteristic from ...
