Op-amp Comparator
The Op-amp comparator compares one analogue voltage level with another analogue voltage level, or some preset reference voltage, VREF and produces an output signal based on this voltage

We can conclude our section and look at Operational Amplifiers with the following summary of the different types of Op-amp circuits and their different configurations discussed throughout
We have seen that we can connect resistors to a basic operational amplifier to produce various inverting and non-inverting outputs and configurations along with their
Here, the position of the capacitor and resistor have been reversed and now the reactance, XC is connected to the input terminal of the inverting amplifier while
Operational amplifiers can be used as part of a positive or negative feedback amplifier or as an adder or subtractor type circuit using just pure
Thus far we have used only one of the operational amplifiers inputs to connect to the amplifier, using either the “inverting” or the “non-inverting” input
We saw previously in the inverting operational amplifier that the inverting amplifier has a single input voltage, (Vin) applied to the inverting input terminal. If
In this configuration, the input voltage signal, ( VIN ) is applied directly to the non-inverting ( + ) input terminal which means that the output gain of the
We saw in the last tutorial that the Open Loop Gain, ( AVO ) of an operational amplifier can be very high, as much as 1,000,000 (120dB) or
We saw in our last tutorial that a permanent magnet moving-coil (PMMC) galvanometer is a type of instrument in which a current carrying coil is
Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or
When analysing the operation of electrical and electronic circuits, or trying to understand why a circuit does not work as expected, eventually you will need
