The 741 op amp comparator circuit is a simple and popular circuit that is used to compare two input signals and produce an output signal that indicates the relative magnitude of the inputs. The circuit uses the LM741 operational amplifier, which is …
Certain electronics application requires high current to drive loads. Op-amp or operational amplifier usually have low output current. For example the uA741 or LM741 op-amp has output current capability of just 25mA. This maybe adequate for most app…
An audio amplifier circuit is a device that increases the strength of an audio signal. One way to build an audio amplifier circuit is to use the LM741 op-amp together with the LM386 audio power amplifier integrated circuits (ICs). The LM741 IC i…
Twin-T is one of several method of build a sine wave oscillator. Here it is shown how to make a twin-T oscillator with LM741 or uA741 operational amplifier. Any oscillators needs two parts- an amplifying part and feedback part. These two parts of o…
uA741 op amp can be used for power amplification and thus be used for driving actuators and motors that requires high power. Here a design of DC motor controller with uA741 op amp is shown. Operational amplifiers like LM741 or LM358 can also be u…
Here it is shown and explained how to build powerful 3W audio amplifier to drive a speaker with LM741 op amp . The 741 operational amplifier IC like LM741 or uA741 are old but still popular op-amp that can be used for many electronics projects. He…
Microphone are electronics devices that are used to acquire audio signal and convert them to electrical signals. Microphone that uses magnets are also called Magnetic Microphone or Magnetic Mic . The audio signal which is converted into electrical …
Audio amplifier are electronics circuit used to amplify audio signals. Such amplifiers can be designed using transistors and operational amplifier. Here we look at audio amplifier design using 741 operational amplifiers(LM741,uA741 and similar 741 …
LM741 operational amplifier is old but very popular op-amp which are still found in the electronics market. Most op-amp works well with dual power supply but many times we do not have proper dual power supply. Op-amp can also be operated using si…
LM741 operational amplifier is old but a popular operational amplifier integrated circuit which is still available in electronics market. In many circuit design it is desired to operate op-amp like LM741 with single supply voltage. Here it is sh…
Here we demonstrate how we can use Matlab Simulink as real time oscilloscope . With the matlab simulink oscilloscope demonstrated here actual signal can be viewed and analyzed in time and frequency domain in real time. This is useful to electronic…
