NJM8532
Rail-to-Rail Input/Output Dual Operational Amplifier
■
GENERAL DESCRIPTION
The NJM8532
is a Rail-to-Rail Input/Output dual operational
amplifier featuring Low power, low noise and operation from 1.8V.
Rail-to-Rail Input/Output provides wide dynamic range, is from
ground to power supply level. In addition to ground sensing
applications, NJM8532 enable to be applied to Hi-side sensing
applications.
The features are low noise and low operating voltage for battery
management, portable audio applications, and others.
