LOW INPUT OFFSET VOLTAGE C-MOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The NJU7051/52 are single and dual 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.
