NJM2732
Rail-to-Rail Input/Output Dual Operational Amplifier
■ GENERAL DESCRIPTION
The NJM2732 is a Rail-to-Rail Input/Output dual operational amplifier
featuring low power, low noise and a low voltage operation from 1.8V.
The Rail-to-Rail Input/Output offers a wide input/output dynamic range from
ground level to supply line, which provides both ground and Hi-side sensing
applications.
The excellent features of low noise, low operating voltage and high phase
margin make the NJM2732 well-suited for various applications such as
battery powered devices, portable audio devices, sensor applications and
others.
