The LM358 (AS358Pp) is designed for general use as amplifiers, high-pass filters and low, band pass filters and analog adders.One of the characteristics of this IC is to be designed to operate with a single static power supply ranging from a minimum of 3 V to a maximum of 32 V although typically there are stabilizing at levels between 5 V and 15 V. In fact, while the majority of integrated circuits containing the operational needs two power supplies, one positive and one negative, the LM358 (AS358P) can be connected to the positive power only while the negative supply is replaced by the mass.
