The integrated operational amplifier OP07 CP is used as the core component,and then a small signal differential amplifier circuit is designed. It is composed of a high input impedance differential amplifier circuit and a general differential input amplifier circuit; then a differential amplifier circuit is obtained,which has high common mode rejection capability,high input impedance and convenient differential gain adjustment. The experimental results show that the effects of amplification of this integrated operational amplifier are ideal.
