LT6375
Tailored precision. The LT6375 delivers 97dB min CMRR, ultralow gain error, drift, and nonlinearity for applications where
a differential signal must be precisely extracted from a common mode of up to ±270V. Precision matched internal resistors
can be configured to match various input ranges, resulting in the best noise, precision and speed for a wide variety of system
designs. The Over-The-Top® amplifier at the heart of the LT6375 enables operation from 3.3V to 50V supplies.
