NJU7029
Low Noise, Rail-to-Rail Output Dual CMOS Operational Amplifier
■ GENERAL 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.
