N-bit DAC based on R-2R weighted resistor architecture

**Library:**Mixed-Signal Blockset / DAC / Architectures

The R-2R DAC is one of the most common types of Binary-Weighted DACs. It consists of a parallel binary-weighted resistor bank. Each digital level is converted to an equivalent analog signal by the resistor bank.

The input/output transfer curve of the binary weighted DAC can be nonmonotonic, which means that the transfer curve can reverse its direction.

The R-2R DAC architecture is low resolution and consumes more power due to the large number of resistors required to implement the architecture.
