nn Space-Saving MSOP and DFN Packages The LT®1997-2 is an attenuating (funnel) difference amplifier that can be used to translate large differential signals to
the low voltage range compatible with ADCs. It combines
a precision operational amplifier with highly-matched resistors to form a one-chip solution to attenuate and level
shift voltages accurately using no external components.
It comes with three standard pin-selectable gain options
(0.1, 0.2 and 0.25), which can be further combined to …
