LOW-POWER AND LOW-OFFSET-VOLTAGE TINY SINGLE C-MOS OPERATIONAL AMPLIFIER

Japan Radio Corporation  

NJU7091A/92A/93A

LOW-POWER AND LOW-OFFSET-VOLTAGE

TINY SINGLE C-MOS OPERATIONAL AMPLIFIER

■ GENERAL DESCRIPTION

The NJU7091A,92A and 93A are single 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 than 1pA,consenquently 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,this series is packaged with very small

SOT−23−5,therefore it can be especially applied to portable items.
