General Description
LMR981G/LMR982FVM/LMR931G/LMR932xxx/LMR934
xxx are input/output full swing operational amplifiers.
LMR981G/LMR982FVM have the shutdown function.
They have the features of low operating supply voltage,
low supply current and low input bias current. These are
suitable for portable equipment and battery monitoring.
