Difference Amplifiers

The dual input, balanced output difference amplifier circuit is shown in the  figure 1.

Figure 1

The Inverting & Non - inverting Inputs:

In differential amplifier output voltage v_O can be given as follows

V_O=A_d  (v₁-v₂)

 When v₂= 0,        
           v_O=A_d  v₁

& when   v₁ = 0,
                v_O = - A_d v₂

Therefore input voltage v₁  is called as non inventing input as a positive voltage v₁ acting alone produces a positive output voltage v_O. Likewise, the positive voltage v₂ acting alone produces a negative output voltage thus v₂  is called as inverting input. Consequently B₁  is called as noninverting input terminal and B₂ is called as inverting input terminal.
