Connect the CRO as per the requirement for voltage and for current measurement.Connect the IC 741 with supply voltages on a bread board.A real op-amp also shifts its operation with temperature. Also the two inputs respond differently to current and voltage due to mismatch in transistors. Current is taken from the source into op-amp inputs. However, a real op-amp does not work this way. Op-amps can perform mathematical operations like summation integration, differentiation, logarithm, anti-logarithm, etc., and hence the name operational amplifier op-amps are also used as video and audio amplifiers, oscillators and so on, in communication electronics, in instrumentation and control, in medical electronics, etc.Īn ideal op-amp draws no current from the source and its response is also independent of temperature. It is measured as µV / V.Īn op-amp is a high gain, direct coupled differential linear amplifier choose response characteristics are externally controlled by negative feedback from the output to input, op-amp has very high input impedance, typically a few mega ohms and low output impedance, less than 100Ω. The variation of the output voltage due to variation of the power given to the IC. Otherwise, it is the output voltage for input zero with unit gain amplification.ĬMRR = Ad / Ac, Differential input voltage is given between V 1 and V 2 and common mode voltage is given as common to both the inputs. Viof = The input voltage for which the output Vo is zero. To measure the Op-Amp parameters and compare them with ideal characteristics.Ī) Input bias current and input offset current.To study the pin configurations, specifications & functioning of IC 741 Op-Amp.Immense knowledge of Op-Amp’s AC and DC characteristics.Pin out of IC 741C with supply voltage rejection ratio.
