NJM2730
Low Supply Voltage Single Operational Amplifier
with Full Swing Input and Output
s
GENERAL DESCRIPTION
NJM2730 is a single supply single operational amplifier with
full swing input and output, operates 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, NJM2730 enable to be applied to
Hi-side sensing applications.
The features are low noise and high phase margin for
battery management, portable audio applications, and others.
Furthermore NJM2730 is packaged with small size package
MTP-5.
