Introduction DAC Digital To Analog Coneverter

Introduction DAC Digital To Analog Coneverter
Digital To Analog circuit can be built easily using the given op-amp input by setting switches that represent the digital scale. Berlogic value "1" if the switch is connected to supply 5 volts and logic "0" when connected with ground / removed. Basic Series Digital To Analog (DAC), there are 2 types:
DAC Type Binary Weigh Resistors

In DAC Type Binary Weight Resistor, installation of the resistors on the inputs Do, D1, D2, ... is as follows: R value in D1 is ½ of the value that is in Do, the R value in D2 is ½ of the value in D1 (or 1 / 4 of R that is in D0) and seterusnya.Pemasangan R value as it is to mendapatkanVoutyang linear (kenaikanper stepnyatetap). Rin sought to make parallel resistor values ​​that exist at each input (D), if the input is masuklebih than one.
 
JenisR DAC-2R LADDER...

 In DAC R-2R Ladder Type Installation of the value of resistors on the inputs it is the R-2R, so that the value of R = 10k, it was installed 20 k.Pemasangan 2R resistor value is as it is to get out a linear V (increase per his step-fixed).
