This pin is the inverting input of first op-amp This pin is the output of first operational amplifier I would appreciate your support in this way! I may make a commission if you buy the components through these links. The LM358 is a versatile uses it can be used as comparator to compare different signals, amplifying signals from a variety of transducers or sensors to dc gain blocks or any op-amp function. Then this IC will decide whether the voltage is greater or less than reference voltage by giving output high or low.
The LM-358 IC get signal from the sensor and compare to the reference voltage.
By using 0.3V we cannot ON/OFF led or relay. We cannot do anything with this rating for example we obtain 0.3V from sensor. Generally we obtain signal from sensor are usually have small rating. LM- The low power drain also makes the LM358 a good choice for battery operation. In this IC we have two operational amplifier which can we use as a comparator. It consists of 8 pins which contains two operational amplifiers. It can handle voltage from 3V to 32V DC supply and current up to 20mA per channel. LM358 IC can also be used as transducer standard operational amplifier and it is suitable for our needs. Single power supply will be required to operate both op-amps in LM358. The LM358 contains two independent high gain operational amplifiers, low power, dual channel op-amp, high gain with internal frequency compensation.
