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. PACKAGE OUTLINE
