The NJU77000/NJU77001 are single 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. 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. 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 AGrade (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).
