nn Space-Saving MSOP and DFN Packages The LT®1997-1 is a difference amplifier that can be used to
amplify small differential signals while rejecting large common mode signals making it an ideal choice for current sense
applications. It combines a precision operational amplifier
with highly-matched resistors to form a one-chip solution to
amplify and level shift voltages accurately using no external
components. It comes with three standard pin-selectable
gain options (10, 20 and 50), which can be further combined
to form gains from 0.141 to 80 with accuracy of 0.012% …
