DESCRIPTION
The NJU77000/NJU77001/NJU77002/NJU77004 is
single/dual/quad ultralow power 345nW/ch operational
amplifiers designed to extend battery life and
performance for portable applications. The operating
voltage range of 1.5V to 5.5V and supply current of
0.29uA(single), 0.23uA/ch(dual/quad) typical, with
stable over temperature and input voltage change
make them ideal for micropower oxygen sensors, gas
sensors and remote sensor applications.
In addition to the ultralow power and low operating
voltage, rail-to-rail input and output, input offset voltage
of 1.0mV(single), 1.3mV(dual), 1.5mV(quad) maximum
with 0.65uV/°C drift, input bias current of 10pA
maximum and ability to drive 470pF loads, make the
NJU77000 series ideal when requiring excellent
performance in battery powered applications.
NJU77000 series are specified normal grade
(NJU7700x) and A-Grade (NJU7700xA). A-Grade is
guaranteed lower offset voltage and supply voltage
from -40 to +105 °C than the normal grade.
The NJU77000 is available in the 5-pin SOT-23
package. NJU77001 is available in the 5-pin SOT-23
and SC-88A package. NJU77000 and NJU77001 have
difference pin function (see pin configuration). The
NJU77002 is available in the 8-pin SOP8: JEDEC
150mil, MSOP8 (TVSP8): JEDEC MO-187-DA / thin
type and ESON that is thin and 2mm square small
packages. The NJU77004 is available in 14-pin
SSOP14 package.
