Datasheet
Low Supply Current Output Full Swing
CMOS Operational Amplifiers
LMR341G LMR342xxx LMR344xxx
General Description
The LMR341G, LMR342xxx and LMR344xxx are input
ground sense, output full swing operational amplifiers.
They have the features of low operating supply voltage,
low supply current and low input bias current. These are
suitable for sensor amplifier, battery-powered electronic
equipment, battery monitoring and audio pre-amps for
voice. Shutdown function is applied to LMR341G.
