Mathematical operations circuit
How to Use Lm258
As we know there are 2 operational amplifiers used in LM258 and connected.
These operational amplifiers are used to work of components as amplifiers, comparators, and oscillators, and perform some math operations.
here we make a circuit by using one operational amplifier of the component.
The operational amplifiers are non-inverting configuration and output is given at Vo. VCC power source connected.
As we know the equation for output Vo is =Input voltage * Gain = Vi * A = Vi * (1+R1/R2)
By putting the value of resistance and input voltage we can find output voltatge.

Lm258 Technical Features
Faqs
What is a dual-operational amplifier?
- The operational amplifiers that come with two power sources are called dual operational amplifiers such as NJM4560 Dual Op-Amp. The positive voltatge is provided at the V+ terminal and the negative voltage is at V-. The input signal of these integrated circuits can vary from +Ve to the -Ve voltage supply.
What is the basic introduction to the operational amplifier?
- The operational amplifier is an integrated circuit that can amplify weak signals. The operational amplifiers come with two input pins and one output pins. Its basic working is to amplify and output the voltage difference of two inputs pinout.
What is the difference between LM258 and LM358?
- LM258 and LM358 are baord both come with low-power dual operational amplifiers. LM258 is an industrial board with having operational temperature value of -25 degrees to +85 degrees.
- LM258 is a commercial-grade chip having a temperature range of 0 degrees to 70 degrees.
- Both come with different input offset current, input offset voltage
What is the difference between LM258 and LM393?
- LM258 is the operational amplifier and LM393 is the voltage comparator. The 1258 is also used for voltage comparsion. LM393 is used as the output of the comparator with that pull-up resistor connected
Can LM258 replace LM348?
- Lm258 is a less power dual operational amplifier that is used for single supply operation. LM348 is a quad-operational amplifier having the same pin configuration as LM324. LM324 is the board that operates through a dual power supply and a combination of 741 boards. The PINs of the two boards are different which causes no direct replacement. The replacement is based on circuit design.
What is the function of the operation amplifier?
- The operational amplifiers work on analog input. It is used for amplification or attenuation of input, and performs mathematical operations like addition, integration, and differentiation.
- Due to the larger number of uses operational amplifiers are encountered in most electric circuits.
