Operational Amplifiers Series
Input/Output Full Swing
Low Power Operational Amplifiers
LMR981G, LMR982FVM, LMR931G, LMR932F, LMR934F
●General Description
Input/Output Full Swing Low Voltage single, dual and
quad Op-Amp integrates into a single chip. Especially,
these series are operable with low voltage and low
supply current. Shutdown function are applied to
LMR981 and LMR982.
●Features
