General 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 0.29µA(single), 0.23µA/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 0.65µV/°C drift, input bias current of 10pA maximum and ability to drive 470pF loads, make the NJU77000 series ideal when requiring excellentperformance 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-23and 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 DFN(ESON) that is thin and 2mm square small packages. The NJU77004 is available in 14-pin SSOP14 package.
