Op-Amp as a Differential Amplifier An op-amp is a differential amplifier which has a high i/p impedance, high differential-mode gain, and low o/p impedance. When the negative feedback is applied to this circuit, expected and stable gain can be built. Usually, some types of differential a...
ST's op amp portfolio provides a unique choice of high performance, low power and precision operational amplifiers in a wide variety of packages.
The operational amplifier (op amp) is an important part of any analog signal chain, often working as a crucial part of the interface between sensors and our world-leading ADCs. Common analog op amp functions include gain, buffering, filtering, and level-shifting. Analog Devices’ portfolio provi...
Adifferential amplifier(also known as adifference amplifierorop-amp subtractor) is a type of electronic amplifier that amplifies the difference between two inputvoltagesbut suppresses any voltage common to the two inputs. A differential amplifier is an analog circuit with two inputs (V1and V2) and...
First to begin with, an op amp is a differential amplifier. This means it amplifies the difference in voltage between the two input pins. Because of this fact, its output should be 0V when there is no difference between its inputs, in other words, when its inputs are at equal voltages...
All simple mathematical operations such as addition, subtraction,comparison, etc. are possible with op-amp application circuits. But, what if we need to integrate a signal? For integration, there is one circuit using an op-amp. By replacing the resistive feedback in the inverting amplifier with...
Using the proposed transconductor, an op amp and a differential difference amplifier (DDA) were implemented in a 1.2-/spl mu/m CMOS process. The transconductor has a total harmonic distortion (THD) of less than -60 dB for an input swing of 400 mV at 10 kHz. The op amp and the DDA...

I'm only getting 7.7 volts. I know that one op-amp rule is the voltages are the same at the inputs but my LM358 is not meeting that. I have the positive input wired at 12V. I have the gain set at 3 (56K/18K) with 12 volts as the input to the negative side. The resulting ...
