DESCRIPTION
The NJU7026/NJU7027/NJU7028 are single, dual
and quad rail-to-rail output single supply CMOS
operational amplifiers featuring low supply current.
These amplifiers operates from single 1.8V to 5.5V
supply or dual ±0.9V to ±2.75V supply and provide a
160kHz gain-bandwidth products while using only 13μA
of supply current per channel, ideal for 2-cell battery
systems and 1-cell li-ion battery systems.
NJU7026/NJU7027/NJU7028 have rail-to-rail outputs
that typically swing to within 50mV of the rails with
100kΩ load and the input common mode voltage range
includes negative supply rail and swing to within 0.9V of
the positive rail. These characteristics make them
suited for low-side current sense applications.
In addition to low power and rail-to-rail output, very
low bias current make them to used for photodiode
amplifiers, charge amplifiers, piezoelectric sensors and
other applications with high source impedance.
NJU7026/NJU7027/NJU7028 are high RF-immunity
to reduce malfunctions caused by RF noises from
mobile phones and others.
The NJU7026 is available in 5-pin SC-88A and
SOT-23 package. NJU7027 is available in 8-pin MSOP
(TVSP): meet JEDEC MO-187-DA / thin type package
and DFN which is thin and 2mm square small package.
NJU7028 is available in 14-pin SSOP package.
