How to Make Own Digital to Analog Convertor R 2R Ladder

Things Required :-

1. Resistors of two different value one resistor should have 'R' resistance and the other should have'2R' resistance. I used 220 for 'R' resistance and 2 x 220 ohm resistance for '2R' resistance.

2. A bread board to place resistors.

3. Multimeter to Check the voltage.

1. V1,V2,V3,V4 are the points were we are going to give digital Input .

2. VA is the Analog reference voltage were we get analog output.
