NJM2741
Single Supply, Rail-to-Rail Output Single Operational Amplifier
■GENERAL
DESCRIPTION
NJM2741 is a low noise Rail-to-Rail Output single operational
amplifier.
Rail-to-Rail Output function provides wide dynamic range, is
from ground to power supply level. And Input range rails from
ground level.
It is suitable for audio section of portable sets, PCs and any
General-purpose applications.
