The noninverting op amp has the input signal connected to its noninverting input (Fig. 2.3), thus its input source sees infinite impedance. There is no input offset voltage because VOS = VE = 0, hence the negative input must be at the same voltage as the positive input. The op amp ou...

An op-amp has three terminals like two inputs & one output, where one of the input is known as inverting input and it is marked with a minus (-) 7). What is the voltage gain of an inverting amplifier? Voltage gain (A)= Vout/ Vin = – Rf/Rin 8). What is the voltage gain of...
Assuming the op amp is ideal, we start with vn = vp. Then since the op amp's noninverting terminal is connected to the source, vn = vp = vs. Because no current flows into the op amp, by KCL we have i1+i2=0 and vsR1+vs-voR2 or vo=(R1+R2R1)vs The overall gain is vovs...
When you setup an LM358 op amp as a voltage amplifier why is it that you use an inverting amp rather than an non inverting amp? ... If you use the non-inverting configuration your gain MUST BE ≥ 1.0 With the inverting configuration your gain can be ≤ 1.0 or > 1.0 Like Reply ...

The non-inverting input of the operational amplifier is connected to ground. As the gain of the op-amp itself is very high and the output from the amplifier is a matter of only a few volts, this means that the difference between the two input terminals is exceedingly small and can be ig...

It sums with the input level being applied to that input. As illustrated in the slide diagram the decision point moves with the offset. In this example, the offset is -10 mV, 0 mV and +10 mV summed with the +2.5 V applied to the non-inver...
