Rail-to-Rail Input/Output Dual Operational Amplifier NJM7 GENERAL DESCRIPTION The NJM7 is a Rail-to-Rail Input/Output dual operational amplifier featuring low power, low noise and a low voltage operation from.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 NJM7 well-suited for various applications such as battery powered devices, portable audio devices, sensor applications and others.
