±270V Precision Difference Amplifier Wide Common Mode Bidirectional Current Monitor 3V – 50V 97dB ±270V CMRR + − LOAD 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.
