NJU7021/22/24
LOW VOLTAGE C-MOS OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION
The NJU7021,22 and 24 are single, dual and quad C-MOS
Operational Amplifiers operated on a single-power-supply, low
voltage and low operating current.
The minimum operating voltage is 3V and the output stage
permits output signals to swing between both of the supply rails.
The input bias current is as low as less than 1pA,consequently
the very small signal around the ground level can be amplified.
Furthermore, the operating current is also as low as 150μA
( typ ) per circuit, therefore it can be applied especially to battery
operated items.
