NJRC NJU7008F3 Low power and low offset voltage super small-sized single c-mos operational amplifier Datasheet

NJU7007/08
LOW POWER AND LOW OFFSET VOLTAGE
SUPER SMALL-SIZED SINGLE C-MOS OPERATIONAL AMPLIFIER
■GENERAL DESCRIPTION
The NJU7007/08 are super small-sized package single
C-MOS operational amplifiers operated on a single-powersupply, low power, low offset voltage and low operating
current.
The input offset voltage is lower than 4mV, and the input
bias current is as low as than 1pA, consequently 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 NJU7007/08 are packaged with super
small-sized SC88A, therefore it can be especially applied to
portable items.

Note1) If the supply voltage (VDD) is less than 7.0V, the input voltage must not over the VDD level though 7.0V
is limit specified.
Note2) The power dissipation is value mounted on a glass epoxy board in size of 50x50x1.6 millimater.
Note3) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the
circuit.
