Abstract
One example includes an R2R digital-to-analog converter (DAC) circuit. The circuit includes at least one scaling circuit configured to apply a scale-factor with respect to a nominal voltage range defined by a low-voltage rail and a reference voltage to define a scaled voltage range. The scale-factor can be positive and less than one. The circuit also includes an R2R ladder circuit configured to generate an analog ladder voltage corresponding to a digital input signal. The analog ladder voltage can have an amplitude in the scaled voltage range. The circuit further includes an output stage configured to apply an inverse of the scale-factor to the analog ladder voltage to generate an output voltage.
