NJU7051/52/54 LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The NJU7051,52 and 54 are single,dual and quad C-MOS Operational Amplifiers operated on a single-power-supply,low voltage and low operating current. The input offset voltage is lower than 2mV,and the input bias current is as low as less than 1pA,consequently the very small signal around the ground level can be amplified. The minimum operating voltage is 1V and the output stage permits output signal to swing between both of the supply rails. Furthermore,the operating current is also as low as 15A ( typ ) per circuit,therefore it can be applied especially to battery operated items.
