[@TechieRohit]

I found it no were on youtube but i find it here..thanku mam

[@circuitsanalytica4348]

In several channels, this is explained....

[@osamajaved7750]

Your explanations are just awesome....just add subtitle plz for much easy.

[@santoshinisagar5129]

Thanku mam gland to have u and fit for teaching may God bless u with more knowledge and happiness

[@thegigglegalaxy123]

Maam, you are very intelligent in electronic............

[@infinityvoid6097]

Thanking u guys from bd... Such a relief that someone has put up a explanation for these topics..Vagwan apka vala kare:3

[@islamicworld2277]

Mam you are an awesome teacher.

[@mithileshvannela8366]

I passed digital electronics because of u mam just one night batting .....

[@AmbatiLakshmi-pb9zt]

Thank you mam

[@sonakshi.3542]

Super mam..TQ

[@rishabhmadys8264]

simple and accurate explanation

[@vedantwadurkar4581]

the MSB RESISTOR SHOULD HAVE A VALUE OF "R" NOT "2R" resistance of lsb is 2^(n-1)R.

[@korraravikumar1394]

It won't starts from 2^0*R, 2^1*R, 2^2*R.... It starts from 2^1R, 2^2R......2^n*R. If you observe the equation of DAC Analog value =K* Digital value. Vo= Vfl(2^-1*d1+2^-2*d2....2^-n*dn).

[@madanmedaramitla5012]

In output voltage formula we have to keep -vr instead of vr

[@abhijitkumarmanna2031]

In negative feedback of opamp the opamp phase shifts the output wrt to input supplied so -Vr is given as input in phase shift it will be opposite +ve

[@purushothamraju7876]

Excellent

[@worldaroundyou7251]

Resistor required in n binary weightage type resistor is not nr or 2r or 4 r ...it is 2 power n-1 R like as for 4 bit binary weighted converter n=4 so 2 power n-1 = 2 power 3 =8 resistor ...

[@cricmaestro1105]

Mam why you are leaving resistances connected to ground here but taking consideration while explaining r2r ladder dac

[@lubna2266]

Thank u very much mam

[@RamuKaka0pYT]

Thank you mam 🛐

[@AshishCE-i3r]

Is really so accurate and now it's easy to get A/d and D/A Thank's

[@circuitsanalytica4348]

Yes, it is really accurate but not as R-2R ladder network DAC

[@crazypen]

LSB or MSB =1🤔🤔🤔

[@bharatvidhani9655]

Mam in problem statement Vr is given ??? If not given then how to find it??

[@theresponsiblecyclist5926]

It will always be given

[@thisissharief7651]

great explantion

[@balajibaheti8577]

Why dont we consider the resistance connected to gnd while calculating the equivalent resistance as in case of R-2R ladder?

[@SupremeTuber]

If you still have doubt on this topic go ckeckout this video it's way better kzbin.info/www/bejne/bV6XZ5mDm82LebM

[@shubhamkumar-jy7se]

thanks

[@sheeya.j365]

its wrong formula vo=Vr/2[b2/2+b1/2^2/bn/2^n]

[@subhasishchoudhury5093]

Thank u Mam... Keep it up n help us..

[@vnktsh1]

You explained very well.. 🌺🌺

[@debapriyasarkar5871]

Thanks mam..awesome explanation..

[@haydermosa3601]

good explain

[@jeslindrusila3500]

If 0, ground will be connected and those resistances need to be included know,as in R 2R ladder. Can any one clear my doubt?

[@vaishnavijasutkar8480]

thanks mam

[@nuthankumar3913]

For 3bit=0011 but why you take 100 mam

[@glassvangaface3064]

sooo Thank you mam....

[@rehameskander]

Very good

[@dmitrov6464]

Thank you mam.

[@bhairajagautam3505]

I think you are mistaken. The MSB should be R , not 2R. So almost every calculation you do is not correct.

[@SuperChazza101]

At least it's almost, not every. Take the positives. You go Mrs India

[@pujithakaricheti8170]

Don't judge a book by it's cover 😂😂just kidding

[@mohanvarri7439]

Madem please take analog electronics classes... Plz madem

[@manthinasatish3661]

Ur voice is so sweet...

[@anthonyronald7566]

thku mam . your lessons helped a lot

[@3kkpower]

Does this mean that when doing this calculation we have to consider one input at a time and then add the individual outputs.

[@abhijitkumarmanna2031]

No you multiple inputs can be given depending on the number of bits if 110 in binary then from msb make two input connected to -Vr and lsb 0 the 3rd input to ground to make 0 the current will be flowing from 1 1 input. Total current will be the sum of 1 1 input current. Now the total current is input to op amp which converts current to voltage. Thank you hope this will help many techies😊

[@khadijasoomro3519]

is required to operate a solenoid valve using a microcontroller-based system. The solenoid valve has two opening positions A and B, the valve opens at position A at a voltage of 0.4125V (scaled) and at position B at a voltage of 2.0625V (scaled). Design a binary weighted DAC that can be used to perform this task. You cannot use a reference voltage higher than 5V. Solution???

[@aradhanajlal4912]

Tnqu ma'am!!

[@SYEDAHMEDABDULQUADEER]

Thank you so much mam...Such a nice explanation🙂

[@prasadp8441]

very helpful

[@AMRESHKUMAR-ol9ei]

mam R= Rf or R= 2Rf both the values are valied ???????????????????

[@thienluucong3358]

If the bit value is 0, i think this resistor will be floating, not connect to GND

[@pujithakaricheti8170]

Actually it is floating I think,for representation purpose they used ground

[@circuitsanalytica4348]

That input is connected to ground, it will not be floating....

[@praveenprakash6896]

resistance of lsb is 2^(n-1)R.

[@sayanpradhan1236]

Thank u mam,u r great 👍👍

[@vikasvikas1921]

the MSB RESISTOR SHOULD HAVE A VALUE OF "R" NOT "2R"

[@Jitendra_2107]

It's binary resistor bro...

[@bablishqi796]

You don't know shit bro

[@Intent123]

why we are considering -Vr as input

[@circuitsanalytica4348]

Hello Krishna, Reference voltage can be either positive or negative.... if ref voltage is negative we will get a positive output else output will be negative...

[@joynusnoronha2047]

Why do u take reference voltage as negative??

[@circuitsanalytica4348]

So that output voltage is positive, you can take in the other way also....

[@swetachaurasia271]

Y rad pen ka use na kre ap smg nhi aa rha h kya likha h

[@Fdjyn]

Why do we take refrence voltage as -Vr

[@circuitsanalytica4348]

If you take Vr -ve, we will get positive output voltage else we will get a negative output voltage....

[@thothireddygovardhanreddy7133]

Pls elaborate the last formula how the a1 a2 a3 are taken?

[@dmitrov6464]

For 110 MSB=1 Therefore in formula a1=1 R=2Rf a2=1. R=4Rf a3=0 Therefore by formula {1/2+1/4+0} Vr =3/4 Vr

[@circuitsanalytica4348]

Hello Mr. Reddy, I had analysed this circuit, you want you can refer my videos....

[@vip_rudra5961]

Write in bigger size so that it will be more visible. Rest is good 👍

[@vaishnavijoshi5665]

Thanks Madam ur Explanation of digital elec is very beautiful it is much valuable.

[@Mayank1008]

Mam can u plz tell why we have used power of 2 with registers in binary weighted register mthod

[@circuitsanalytica4348]

Hello Munesh, digital value is actually binary weighted - consider 111 ie decimal 7- 1 × 2^2 + 1 × 2^1 + 1× 2^0, so amount of currents through these resistors are also binary scaled - let current through MSB resistor is 4mA, current through next resistor is 2mA and current through LSB resistor is half of current flow through resistor of the previous bit....
