NJU7042
INPUT/OUTPUT FULL-SWING
TINY SINGLE C-MOS OPERATIONAL AMPLIFIER
sGENERAL
DESCRIPTION
The
NJU7042
is a single C-MOS operational amplifier
permitting input and output in full swing.
The operating voltage is 2.7V to 5.5V and the input and
output stage permits signal to swing between both of the
supply rails.
The input offset voltage is lower than 5mV, and the input
bias current is as low as than 1pA, consequently very small
signal around the ground level can be amplified.
Furthermore, The
NJU7042
is packaged with very small
MTP-5, therefore it can be especially applied to portable
items.

Note1) If the supply voltage (V
DD
) is less than 7.0V, the input voltage must not over the V
DD
level though 7.0V is
limit specified.
Note2) Decoupling capacitor should be connected between V
DD
and V
SS
due to the stabilized operation for the
circuit.
