What are Opamps?

What are Opamps and Comparators? Opamps are differential amplifiers that amplify the differential voltage between the positive/negative input pins.
Op Amp/Comparator Circuit Configurations Generally, opamps are broken up into 3 stages: Input, Gain, and Output.
Op Amp Types Op amps can be classified into 3 main types based on the input/output voltage range.
Noise Characteristics (EMI/EMS) Noise is commonly referred to as EMC, but when used in certain fields it is broken up into two types, EMI and EMS.
Typical Parameters of Opamps When a voltage is supplied to the input of the amplifier circuit it is multiplied by the amplification factor and appears at the output.
Absolute Maximum Ratings The absolute maximum rated supply voltage is the maximum voltage that can be supplied between the positive supply (VCC) and negative supply (VEE) pins.
