NJU7091A/92A/93A LOW-POWER AND LOW-OFFSET-VOLTAGE TINY SINGLE C-MOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION PACKAGE OUTLINE 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. NJU709XAF 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 SOT235,therefore it can be especially applied to portable items.
