NJM2732
Full-Swing Input and Output type Dual Operational Amplifier
■ GENERAL DESCRIPTION
NJM2732 is dual operational amplifier with full swing input and
output, operate from 1.8V.
Input and Output Full Swing provides wide dynamic range, is from
ground to power supply level. In addition to ground sensing
applications, NJM2732 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.
