LT6375IDF#PBF

LT6375 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. Comparing the device to existing difference amplifiers with high common mode voltage range, the selectable resistor divider ratios of the device offer superior system performance by allowing the user to achieve maximum SNR, precision and speed for a specific input common mode voltage range. It is widely used in application such as high side or low side current sensing, bidirectional wide common mode range current sensing, high voltage to low voltage level translation, precision difference amplifier, industrial data-acquisition front-ends, replacement for isolation circuits etc.
