Abstract
A digital to analog converter (DAC) includes a first sub-DAC configured to convert most significant bits (MSBs) of digital input data, the first sub-DAC including a first array of resistors, a second sub-DAC configured to convert at least some least significant bits (LSBs) of the digital input data, the second sub-DAC including a second array of resistors, and a first scaling resistor connected between the first and second sub-DACs, wherein the first scaling resistor has a resistance value that is based on the number of resistors in the second sub-DAC.
