R2R DACs

A R-2R DAC (Digital-to-Analog Converter) is a type of resistor-ladder based DAC that converts digital binary signals into analog voltages or currents. The defining feature of R-2R DACs is that they use a network of resistors arranged in a ladder-like configuration, employing only two resistor values: R and 2R (where 2R is double the value of R).
