Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge on Introduction to LM348. LM-348 i basically a General Purpose (GP) Operational Amplifier. It is an independent and quadruple operational amplifier. LM 348 has similar characteristics in comparison to uA741. It is an internally compensated amplifier having high gain. LM-348 has four internal amplifiers. We can achieve isolation between these amplifiers by biasing each of the amplifier independently. This isolation can be done using different techniques e.g. layout technique. It can be used at several different places where amplifier matching is needed. LM 348 has very low supply current drain as compared to the standard 741. Moreover, Its input voltage and input offset current is ...
Hello everyone! I hope you all will be absolutely fie and having fun. Today, I will elaborate you about Introductio to NE556 timer IC. NE-556 is a lot stable monolithic device. We can use precise delays and oscillation by using this device. NE 556 is bsically an dual version of NE 555 timer IC. Timing is provided for each function using an external capacitor and resistor. There are two internal timers which operates independently. They just share common power supply and ground. For the falling or rising wave forms we can trigger or reset the entire circuit. The trigger level and the threshold levels are usually one third and two third respectively. We can alter both of these level by using control pin of NE-556. If the input at trigger falls below the level of the trigger, flipflop is adju ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to MMBD914. MMBD 914 is basically a switching diode. A switching diode has the functionality similar to the switch. Like an open switch, MMBD 914 has a high resistance for the particular applied voltage. Switching diodes are usually used in different device e.g. ring modulation. The right switching diode can be chosen keeping in mind our requirements e.g. reverse recovery time, power dissipation and maximum peak current etc. I have also written an article on another switching diode, Introduction to 1N4148 , and this my second article on switching diodes. MMBD-914 has a vey wide range of applications including high speed switching, high speed rectification purpos ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to elaborate you about Introduction to L298.

Hello everyone! I hope you all will be absolutely fine and having fun. I am going to elaborate you on Introduction to LT1054. It is a monolithic device. LT-1054 is also known as voltage regulator and bipolar capacitive voltage converter. Its mean feature is that it provides very low voltage losses as compared to the other common converters. LT 1054 also provides large output currents in comparison to general converters. It provides a voltage drop of around 1.1V while operating at 100mA. LT 1054 provides us with a feature of regulation. This feature was not available in earlier voltage converters. We can get a regulated output just by inserting an external resistance. We can shut down LT-1054, if we ground its feedback terminal. Its internal oscillator works at 25kHz frequency. Switching fr ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 74HC245. 74HC 245 is a eight (8) bit transceiver. It has three (3) output states. 74HC-245 is designed for a-synchronous transfer of data between different data buses. The external timing requirement can be reduced by the implementation of control function. You should also have a look at Introduction to 74HC595 . There are two internal amplifiers in 74HS 245. They are named as A and B. Data is transferred from A amplifier to B amplifier and vice versa. Hence two way communication is done in 74HC-245. This communication depends upon the logic level on the direction control input (DIR). Out enable pin (OE) is used to enable and disable the device depending upon ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to given elaboration on Introduction to L293D. L 293D is basically a high current dual motor driver/controller Integrated Circuit (IC). It is able to drive load having current up to 1A at the voltage ranging from 4.5V to 36V.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you about Introduction to LM1458. Lm 1458 is basically a general purpose dual Operational Amplifier (Op-amp) i.e. it consists of two internal amplifiers. The internal amplifiers has both common power supply as well as common biased network. This is done so that their operation remains dependent on each other. If the power supply and biasing is not common then they will be totally independent. LM 1458 is a device which is protected from short circuit and it requires no external components for the frequency compensation. LM 1458 is considered to be and ideal amplifier for voltage followers. This is due to its latch-up free operation and high common mode voltage range. LM 1458 has amazing fea ...
