General 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 0.65µV/°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.
