NJU7029 Series
Low Noise, Rail-to-Rail Output Dual CMOS Operational Amplifier

Download Datasheet

  • Description

    The NJU7029 is a dual CMOS operational amplifier with a low noise of VNI=13nV/√Hz (typ. @f=1kHz), Rail-to-Rail output and low operating voltage. It offers a single supply voltage operation from +2.2V to +5.5V, rail-to-rail output swing in both supply rails and input voltage range from ground. Further the NJU7029 has a low bias current of 1pA, which makes it well-suited for current sense amplifiers such as an acceleration sensor, shock sensor and photodiode amplifier. The NJU7029 is available in small surface mount packages of SSOP8, MSOP8 (TVSP8) and an ultra small lead-less package of ESON8 which allows high-density mounting.
