LM358N Applications

The LM358N IC is used in a wide range of applications as it has a wide operating voltage range and low power consumption. It is used in audio amplifiers, filters, oscillators, etc. It is also used for robotics and instrumentation applications as an op amp. The high input impedance of the LM358N enables it to be used for voltage amplification and signal conditioning. It is also used for the generation of time delays and for the generation of rectangular pulses. It can also be used for the conversion of analog signals to digital signals and vice versa. The LM358N can also be used for signal isolation as well.

Working Principle

The LM358N is a dual operational amplifier integrated circuit. It works on the principle of negative feedback. The flow of the signal is such that the output signal is passed back to the input, and then this feedback signal is compared with the input signal. If the two signals differ, then the difference is amplified and passed back as the output. This feedback helps in stabilizing the output and controlling the gain of the circuit.

Conclusion

The LM358N is an integrated circuit that is widely used in electronics. It is an inexpensive IC which comes in SO packages of 8, 14, and 16 pins. It works on the principle of negative feedback and thus provides stability to the output and has many applications ranging from audio amplifiers, filters, oscillators, and robotics applications. It has a wide operating voltage range and also a low power consumption.
