The R-2R ladder network in a DAC generates a binary sequence of output current. Each ladder element pair is switched in or out by it's associated control bit so the total output current is the sum of the binary control input word.
Crutschow: AND_ECE is pretty hopeless, just ask blueroomelectronics. We joke about his burgular alarm almost anytime he is on. He is a 4TH YEAR EE STUDENT...
YES!!! OF COURSE A TRANSISTORIES BUGLAR ALARM!!THANKS TO YOU.....
WHY? SOMETHING WRONG? IAM HERE TO ASK QUESTION AND GET IDEA FROM PEOPLE IN THE WHOLE WORLD!LIKE YOU....CAN YOU GIVE ME IDEA! WHAT IS MEAN THE FUNCTION OR PURPOSE OF 2R AND R IN THE LADDER CIRCUIT SPECIAL USE IN DIGITAL TO ANALOG CONVERTER!! PLEASE? OR THE PRINCIPLE OF THE LADDER CIRCUIT

SO EXAMPLE...IF IT IS LOOK LIKE A WINDOW, SO THEREFORE IT IS ALSO CALLED WINDOW NETWORK??? IS THERE ANY EXPLANATION!!I ASSUME THAT U KNOW SO MUCH ABOUT A LADDER NETWORK BECAUSE I THOUGHT THAT YOU WOULD GIVE ME A ANSWER THAT COULD SATISFY ME.

A further explanation: A ladder network consists of pairs of resistors with one resistor twice the value of the other, thus the R-2R designation. There is one pair for each bit of resolution in the DAC. Typically when the network schematic is drawn for all the bits it has a regular pattern that resembles a ladder. Thus some engineer in the distant past named it a ladder network.
