CHARACTERISTICS OF IDEAL OP AMP Here we are going discuss about the Ideal OP-AMP characteristics or assumptions. An operational amplifier is said to be IDEAL if it has the Following CHARACTERISTICS :- 1. Its open loop gain A is infinite. When an operational amplifier (OP-AMP) is operated without any connection between the output and any of the inputs (without feedback), it is said to be in OPEN LOOP condition. Infinite voltage gain means the voltage difference required between the two inputs to produce any output voltage is zero. 2. The Input Resistance should be Infinite. The Input current is zero and so it doesnot load the source. It is also means the ideal OP AMP is a voltage controlled device. 3. The output Impedence should be Zero. The output voltage Vout doesnot depend on the Load Resistance connected between the output terminals. So the output voltage is independent of current drawn by the Load. Thus the device can drive Infinite number other devices. 4. Perfect Balance Because...
