Binary Weighted Resistor DAC Explained
ALL ABOUT ELECTRONICS
IN This video, let 's understand in detail about the
binary weighted resistor type of the type of [UNK].
THe resolution of the [UNK] or [UNK] is de ned in the
number of bits. THis resolution decides how closely
the output of the [UNK] matches with the actual
waveform. And by increasing the resolution, This step
size can be reduced. IF. We change the code by 1
[UNK],, then the output will change by 0. 625 V or by
5/8 V. SO,. We can say that the voltage which is
required is equal to 0. [UNK] The maximum output
voltage which we can get from the [UNK] is known as
the full-scale output voltage. IF. There is any kind of
internal gain,, then this Vref will get multiplied by the
factor K. THis [UNK] can be designed by using the op-
amp as a summing ampli er. We have already.
Already discussed in the earlier video that how the
summing. ampli er can be used to convert the digital
input bits into the analog output.. THe weightage of
each resistor is in the multiple of 2. According to the
binary number, the resistors are connected to either a
reference voltage or the ground terminal..
THe value of 1 [UNK] is equal to 0. [UNK] That means
if we use the resistor with 1 % tolerance, then the
maximum error in the output will be more than 1. TO.
Avoid that the tolerance of all resistors should be less
than 1 %. ANd it hard to achieve as the number of
