- {738} Comparator Circuit Explained, Comparator Circuit Using Single Supply Quad
Comparators LM339, LM339E, LM239, LM2901, LM2901E, LM2901V, NCV2901, MC3302 These comparators are designed for use in level detection, low−level sensing and memory applications in consumer, automotive, and industrial electronic applications. These quad comparators feature high gain, wide bandwidth characteristics. This gives the device oscillation tendencies if the outputs are capacitively coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (VOL to VOH). To alleviate this situation input resistors 10 k should be used. The addition of positive feedback ( 10 mV) is also
recommended. It is good design practice to ground all unused input pins.
Differential input voltages may be larger than supply voltages without damaging the comparator inputs. Voltages more negative than −300 mV should not be used. The LMx39 and LM2901x are quad comparators with the ability to operate up to an absolute maximum of 36 V on the supply pin. This standard device has proven ubiquity and versatility across a wide range of applications. This is due to very wide supply voltages range (2 V up to 32 V), low Iq, and fast response of the device. The open-drain output allows the user to configure the output logic low voltage (VOL) and allows the comparator to be used in AND functionality.
The comparator operates solely as a voltage comparator, comparing the differential voltage between the positive and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input
differential polarity.

ماشااللہ آللہ پاک آپ کو صعت دے بہت ھی اچھے طریقے سے سمجھاتے ھیں ۔
Very nice and simple explanation that a person with little know how of electronics can understand the working of these specific ICs. I really admire your efforts.
Sir me aik textile mill me job karta hu electronics lab me app ki video bhut faida dy rahi hai allah app ko is ka ajjar dy
VeryVery नॉलेज बल video दी गई है sirji thanks
Masha Allah Sir
Bahut hi lajawab video.Iska wait main bahut dino se kar Raha tha or iske baare me Apke saare videos ko check bhi Kiya. Finally aaj Apne iska video banadiya.
Jazakallah sir.Best wishes for you and your family.
Sir ji aaj aapane is video ke jariya mere fasa hua muscal kam asan kar diya hai sir ji bahut bahut shukriya sir ji
جزاکم اللہ خیراً کثیرا
thanks a lot dear brother
sir gi is tapic ko mazeed chalain buhat kuch sekhnay ko milta ha shukriya
MashaAllah ❤️☺️
Jazak Allah ❤️
thanks a lot bhai
Very good explanation sir, All doubt cleared. Thank you so much
Sir waiting for next video..👍🏻👌🏻
Great sar the best
Apka samja ne ka tarika pasand aagaya
GOOD TICHING KARTE HO AP THANKS 👍👌👍👌👍👌👍👌👍
Thanks for explain with easy way.
Good work sir thanks
ماشاءاللہ
Very good explained sir, Thanks for sharing
most welcome
Bahot Alla Zabardast Chha Gaey ho
thanks a lot dear
Excellent thanks for sharing this informative video
AOA. Haseeb sahib good explaination.old timer & customer since you opened shop at DAV Collage Rd. MAHMOOD ALI .Rtd. Chief Engineer Allama Iqbal Open University Islamabad.
welcome dear sir
i am thankful for your valuable comment
i am Muhammad Ashraf form Pakistan but now in Jordan
Excellent
Thank you so much 😀
Thanks a lot of you sir
Most welcome
Aslam u elikum bhai good morning great video mashaAllah
wa alikum salaam dear sister
nice video sir thanks
best regards bhai
Very nice video sir
Thank you
best regards and most welcome
Thanks dear
V.informative .
Dear sir my humble request to please guide for making static voltage stabilizer circuit diagram where input voltage range 110 to 280 and output fixed 220 volts. The transformer used in this traditional laminated EI iron core 50HZ. Please provide a switching circuit diagram for this. Transformer capicity is 3 KW. Sir my mean i need static voltage stabilizer circuit diagram.
Good
Thank you sir 🙏
very nise vido sir jee
Thanks sir ji....
it is my pleasure
Nice vidio ♥️♥️
Very good explanation, sir please make video on non-inverting input .
Thank you and please tell me from where I can buy this test board for experiment
Thanks sir ji
👌👌👌👍
Sir ye LM 339 ic New Kharid Ne Par BLANK Milta ya Programming Kari Hui IC Milta
Please tell me
Sar ji uske upar pure video Ban chuke hain kya
Good evening
Sir, please make vdo on LM324, PLEASE
Sir, i request you to upload a video on MOV.Thanks.

❤🎉
Sir 12 volt ko 2k ohm k bad keo GND kia agr esko GND NH kry to kia hota
Pranam sir jee
Dear sir please hvp-90 this power stematic diagram please available
sr tl494 bary b 1 achi video bnwo
sir iska dusra part ki video banaye please
yes brother all videos are in line. i am planning to share everyday 6 PM Pakistan time
Hello sar ji circuit me lm358 ic parectical testing videos banaye sar uske ham keshe pahchan kare voltage hai low banra he parectical video banaye sar please
Assalam o Alaikum sir electronics Ka online course Karna koi chennal hai Aap Ka sir basic say
Sir please bldc celling fan circuit diagram per aik video banayie please
OUTPUT HIGH HOTI HAI LEKIN KITNA VOTE AATA HAI VAH NAHIN BATAYA. DONON KA DIFFERENCE PIN KA VOLTAGE AATA HAI YA FIR JO POSITIVE SUPPLY DI HOTI HAI IC KO VO ATA HAI.
surkhi, poder😄😄
hahahahaahahha
+ - dual smps making tutorail
Dell HP computer SMPS full stating se vidio
Sir G ❤LM324 IC ka test circuit kese banae
Thanks sir ji
👌👌👍
