Application input end zeroing circuit diagram
In figure (a), it uses a small resistor R5 connecting in the return circuit of R1, the offset voltage produced by R5 and R3 are added to the left end of R1.And the voltage will be divided by R1 and R2. So the offset voltage adjustment range is determined by the following formula: Offset voltage adjustment range = ± VD · (R5/R3) · (R2 / (Rl + R2)) (± VD = ± l5V). According to the resistance value shown in figure (a) , the offset voltage adjustment range is: ± 15mV. R1 = R2. Therefore, the voltage gain of the circuit is low. Taking the R5 and R1 are in series into account , the voltage gain Av: Av = 1 + R2 / (Rl + R5)   (View)
