For the remainder of the circuit (a simple unit-gain summing network) we have chosen an LM358 op-amp, which is a low-power device that can be operated from a single voltage supply, therefore appropriate for battery-operated circuits. Low-power op-amps draw very little quiescent current and hence help prolong the life of the battery. The LM358 is a

When an opamp is operated in its linear mode (which is most of the time for audio and most other amplification circuits), the negative feedback circuit will cause a voltage to appear on the inverting input (-in) that is (almost) exactly equal to that present on the non-inverting input (+in).
