The binary to decimal no. conversion of 1111 is 15 but or ans is 30volts. The resistance you have taken are standard for this wighted circuit or I could have taken R/2, R/4, R/8 and R/16 to make it 15volts according to binary digits?

Hello Mate,Thank you for writing in .Infact this questions is the basic doubt students have . The Analog to Digital Converter is a circuit to convert continuous changing signals into a two state signal Digital signal . These circuits are not Binary to Decimal Converter .Although they do achieve this function .Here what is considered the reference voltage which you feed in the circuit .The reference voltage will be the maximum voltage achieved. Lets say if you have two bit counter -you will reach from 0 to max referenc voiltage in 4 steps and if you have three bit then you will reach in 8 steps and will have a better resolution .Now coming to your question if you desire that this should be a exact Binary to decimal converter than you should give a reference voltage of 15 volt to a 4 bit counter keeping the above resistance values same.

Hello Mr. Trumptge output voltage depends on resolution and polarity of output voltage depends on polarity of reference voltage. If resolution is 0.5V for a 4 bit DAC, then output voltage will be 7.5 V if input is 1111 and if resolution is 2V, than output will be 30V when input is 1111....

@Rohit ,I am glad that you asked this question and infact this is the major confusion we all have .In A/D converters, we are converting an analog signal into Digital format - what we are not doing is converting Decimal into Binary and Vice versa. So ,its all about spliting a voltage range in fractions which is called as resolution .For 4 bit -you will have 2^4 = 16 stages .i.e whatever reference voltage you will provide ,you will get 16 fractions of it .So its V ref which you provide is the highest voltage and the digital states corresponds to its fractions.Let me know ,if I am clear to you else I will explain with examples.

Rajendra Kumar ,Hi Rajendra .......whenever LSB changes ,it means the minimum increment /decrement which will happen in analog voltage from the previous voltage state.Now as you see for all Bits High...it is giving me 30 V and when only LSB is high ,its contributing 2V which is only 1/15 of the maximum voltage. So make a general formula what we do is 2^n - 1 which is an odd number (15) if n=4.Similarly you can do for any number of bits and generalize a formula

Jeremy Crichton Hi Jeremy, Binary word is nothing but a voltage level....... 1 means 5 V or any other defined voltage and 0 means 0 Voltage. So to pass a binary word, the voltage change is sufficient. Here I have added a switches to simplify, rather on the voltage line V1,V2,V3........when the voltage switch will take place from 5v to 0 volt or the other way around...... Binary word will be transmitted by default.

Udta Parinda Thanks for your reply. I have outputs from some Mass air flow sensors uncalibrated. The mimumun value must be between 0.7 and 1.1 Volts but they are from 1.9 to 2.5 Volts. I am triyng to put them in right value range. I think that is a good idea to use this circuit with V1=V2=V3=V4= 0.8 Volts Thus my LSB will be 0.1V. And using BCD dip switch I can select from 0.1V to 1.5V to substract from my V sensor. I tried the same configuración you showed with V sensors in non invertir input of op amp and R=10k with Tl062 op amp Vcc= 12 Volts. It didnt woks in breadboard and I tried to run in simulador using some different op amps and got different outputs but no one substracts BCD value combinations selected. Have you an email that i can send you simulator screenshots?

7.10 : That's insane, you can't cancel Rf and R, they aren't equal. Or rather, they shouldn't be equal because Rf shouldn't be fixed. Rf varies depending on what is the magnitude of maximum voltage , ie, analog output voltage for 1111 digital input,required for one particular set of readings. If you fixate Rf as = R, you'll get only one particular fixed set of readings. The Mumbai Uni at least does not allow you to work with fixed Rf.
@udtaparinda8764

Nikhil Kapoor Hi Nikhil, The maximum voltage for 1111 should depend on the reference voltage which you generate.Rf is used for gain control .If I am assuming Rf = R ,it means I making the gain factor as unity and solely depending on the reference Voltage V.There are two ways either I change Rf or I change V.Normally in A/D concept ,its the V which decides the maximum voltage for 1111.But as you said even Rf decides in this scenario.... I utilizing the concept of V as ref to define max voltage .
@TheDeathstriker123
7 жыл бұрын
Udta Parinda You're right, Rf affects gain. Rf=R will indeed make the gain unity. But In all Mumbai Uni TYBSC physics colleges, Vref (or Vin rather) is kept fixed, and Rf (usually a potentiometer type variable resistor) is changed for different sets of readings. Maybe it's different in other states. Since you didn't mention your comment in the video I thought something was off since I was told to vary Rf by my teachers. Nonetheless, I understood what you said, your comment was accurate. Thankyou for your help in clearing my confusion!

In digital Binary - every bit on the right from LSB increases in weight by power of 2.The LSB has a weight of minimum power of 2 and MSB has a weight of maximum power of 2 . Proportionally every bit weight increases in a power of 2 hence when we use resistor we can use any value but the increment is to be in power of 2.

@udtaparinda8764
5 жыл бұрын
Hi Joseph ,this is the reason why the RANGE of D/A converter is defined .Within this range you have to provide the input so that the output does not exceeds the saturation voltage . While designing its ensured that the maximum output voltage does not exceeds the Power supply given to OP-amp. Incase if it exceeds,the results will be unreliable . So lets say you get a maximum output as 30 V for 1111 , its ensured that saturation voltageof opamp is more than 30 V
