Lab#9 Statement: To study the Non-inverting operational amplifier and calculate its gain. Operational amplifier lab trainer DC power supply Digital Multi-meter AC power source IC # 741 Theory: Non-inverting amplifier means that its output and input voltage signals are in phase. In this amplifier input signal is applied to non-inverting and feedback resistor R 2 is connected between output and inverting terminal. For non-inverting amplifier r in is infinity in ideal case. I f = I in + I B I f = I in + 0 (V o -V B )/R f = (V B -0)/R in (V o /R f ) – (V B /R f ) = V B /R in (V o /R f ) = (V B /R f ) + (V B /R in ) V 1 =V 2 (Virtual Ground assumption) V B = V in V 0/ R f = V in /R f + V in /R in V o = V in (R f /R 1 + 1 ) R f = R in = 1KΩ V o = V in (1+1) V o = 2 V in Procedure: First of all I took a DC power supply and DMM. After this I applied +12V to +Vcc
