LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
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 15µA ( typ )
per circuit,therefore it can be applied especially to battery
operated items.
