DESCRIPTION
The
NJU77000/NJU77001/NJU77002/NJU77004
are
single/dual/quad ultra-low power CMOS operational
amplifiers designed specifically to extend battery life and
performance for portable applications. The supply voltage
range is 1.5V to 5.5V and supply current is 0.29µA typ. (single),
0.23µA/ch typ. (dual/quad). The supply current is stable
against ambient temperature and voltage change, making
them suitable for micro power oxygen sensors, gas sensors,
and remote sensor applications.
These devices also feature rail-to-rail I/O and input offset
voltage of 1.0mV max. (single), 1.3mV max. (dual), 1.5mV
max. (quad).
Moreover, this series has excellent
characteristics ideal for battery-powered applications, such as
0.65uV/°C typ. input offset voltage drift, input bias current of
10pA max. and ability of capacity load drive of 470pF.
NJU77000 series has normal grade (NJU7700x) and A-
Grade (NJU7700xA). A-Grade has improved offset voltage
and supply voltage than normal grade, and other
characteristics are also guaranteed from -40 to 105 °C.
The NJU77000 is available in a 5-pin SOT-23 package.
NJU77001 is offered in 5-pin SOT-23 and SC-88A packages.
NJU77000 and NJU77001 have different pin functions (see
pin configurations). The NJU77002 is offered in 8-pin SOP
JEDEC 150mil
, MSOP (TVSP
JEDEC MO-187-DA / thin type)
and DFN
(ESON) that is thin and 2mm square small package. The
NJU77004 is a 14-pin SSOP package.
