Webprecision DACs are mostly used in pseudo DC applications, the noise problem caused by the feedback resistor in the external current-to-voltage converter [23] (not shown in Fig. 2) is negligible, since the bandwidths of high-precision DACs are narrow. Furthermore, the output impedance of the current-mode R-2R DAC changes with the code, which ... Web2.0 V. Mismatched impedances in the “2R” legs of the R-2R ladder create linearity errors at the DAC output. The 2R resistors are often trimmed to match one another and ideally the MOSFETs in each of the DAC switches is exposed to the same biasing scheme and …
