Ideal characteristics of op amp 15/a/3/1

 

Characteristics of an Ideal Op-Amp
• Infinite input impedance
• Zero output impedance
• Zero common-mode gain, or, countless common-mode
rejection
• Infinite open-loop gain
A
• Infinite bandwidth.
• Since the correct op-amp responds best to the distinction between the
enter alertsthe right op-amp keeps a zero output sign
when the 2 input signals are equal.
• When the two enter indicators are unequal, there is what is called a
common-mode input sign.
• For the precise op-amp, the common-mode output sign is 0. This
function is referred to as common-mode rejection.
• Another characteristicdue to the fact op-amp is biased through both superb and
negative electricity supplies, maximum op-amps are direct coupled devices (no
coupling capacitors are required on the enter). Accordingly, the two
enter voltages can be DC.
• Because the OP consists of transistors biased inside the active region
via the DC strength supply, the output voltage is limited.
