NJU7071/72/74
LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The NJU7071,72 and 74 are single, dual and quad C-MOS
Operational Amplifiers operated on a single-power-supply 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
single around the ground level can be amplified.
The minimum operating voltage is 5V and the output stage
permits output signal to swing between both of the supply rails.
Furthermore, the operating current is also as low as 0.6mA
( typ. ) per circuit, therefore it can be applied especially to
battery-operated items.
