New JRC, introduced single CMOS operational amplifiers featuring an ultra-low operating current of 0.29µA

Nov 29,2012

Well suitable for health-care devices

Tokyo Japan, November 29, 2012- New Japan Radio Co., Ltd. (New JRC) has introduced to the market the NJU77000/001*1 and the NJU77000A/001A*2, single CMOS operational amplifiers featuring an ultra-low operating current (0.29µA typ.) that is the highest ranking in the industry.*3

The NJU77000/001 and the NJU77000A/001A are single CMOS operational amplifiers with an ultra-low operating current (0.29µA typ. VDD=+5V), low voltage operation (+1.5V min.), high precision (offset voltage : 0.35 mV typ. / temperature drift : 0.65µV/°C typ. ), low bias current (1pA typ.) and Input/Output Rail to Rail that are suitable for sensor applications.

Furthermore, they have useful functions such as RF noise immunity, high tolerance to capacitive oscillation and two types of pin assignment, which can provide easiness to design and handle to engineers.

Combining theses performances, the NJU77000/001, and the NJU77000A/001A can provide a long life operation to battery operating devices with sensor circuits, such as health-care devices and gas detectors.

*1 The pin assignment is the only difference between the NJU77000 and the NJU77001.

*2 The NJU77000A/001A offer guaranteed low operating current over the extended temperature range of –40°C to +105°C.
