No real amplifier is ideal, but an op amp can come close, at least with regard to gain at low frequency. The typical IC op amp has an open loop gain of 10^6 and a low frequency input impedance of about 10^12 ohms. We’ll see shortly how such high open loop gain is harnessed to create user-desired gains.

3 More Characteristics of Op-Amp • Since the ideal op-amp responds only to the difference between the two input signals, the ideal op-amp maintains a zero output signal
An operational amplifier (op amp) refers to an integrated circuit having well-defined operating characteristics. We will be looking at those operating characteristics. We will be looking at those operating characteristics.
A practical or real op-amp has some unavoidable imperfections and hence its characteristics differ from the ideal one. A real op-amp will have non-zero and non-infinite parameters. A real op-amp will have non-zero and non-infinite parameters.
Two of the characteristics can be attributed to the internal compensation capacitor of the 741 Op amp. In this experiment, the input bias current, output offset voltage, slew rate and power bandwidth will be measured or calculated and compared to the rated values in the manufacturer’s data sheets. The power bandwidth and slew rate will be measured on breadboard circuits.

An important characteristic of any amplifier is its frequency response, in the ideal amplifier its frequency response should be infinite, it will amplify any and all frequencies equally. In practical amplifiers this is difficult/impossible to achieve, and not always desirable, but op amps have extremely wide, and easily variable bandwidths.

IDEAL OP AMP ATTRIBUTES chip, which could cause a change in the dc characteristics of the op amp itself. Also the heat generated by the dissipation could eventually cause the junction temperature to rise above the 150°C, the commonly accepted maximum limit for most semiconductors. The junction temperature is the temperature at the silicon chip itself. On the other end of the spectrum, if
However, in practice no op-amp can meet these ideal characteristics. And as you will see, a little later on, there is no such thing as an ideal op-amp.
