With that we have realized the amplifier circuit of op-amp and in a similar way we use the device to design all other application circuits of op-amp. Say R1 = 100, R2 = 10 and Input voltage Vi = 20mV We have the equation for the output Vo =Input voltage * Gain = Vi * A = Vi * ( 1+ R1/ R2) Also the device is powered from single voltage source of VCC. Ever want an app to do simple circuit analysis on your phone or. In the above circuit the op-amp acts as a Non-Inverting Amplifier (Since input is given to Non-inverting terminal of op-amp) and output is provided as Vo. Queries such as op amp lead to op amp calculators and Ohms Law leads to. Now let us take a single op-amp from the two and construct a simple application circuit as show below. So we will construct a simple Non inverting amplifier to understand the use of device. Here theses two op-amps can be used to realize any of op-amp application circuits like amplifier, comparator, oscillators and mathematical operations. The device is popular among hobbyists and engineers for being low cost and good performance.Īs mentioned earlier there are two op-amps in the LM258 IC and they are connected internally as shown below. In addition with two of those op-amp on board the device can perform two different functions at a time which comes in handy in applications. For example, these devices can be operated directly from the standard 5V supply used in digital electronics without additional -5V supply. Moreover the device specifically designed for applications like transducer amplifiers, dc amplification blocks to be implemented more easily in single-supply-voltage systems. LM258 IC can be used to realize general purpose op-amp operation circuits like comparator, differential amplification or mathematical operations.
