nn Space-Saving MSOP and DFN Packages The LT®6375 is a unity-gain difference amplifier which
combines excellent DC precision, a very high input common
mode range and a wide supply voltage range. It includes a
precision op amp and a highly-matched thin film resistor
network. It features excellent CMRR, extremely low gain
error and extremely low gain drift. nn APPLICATIONS High Side or Low Side Current Sensing …
