Analog Devices Inc. LT6375 Voltage Difference Amplifiers
Analog Devices Inc. LT6375 Voltage Difference Amplifiers are unity-gain difference amplifiers that combine DC precision, high-input common mode range, and wide supply voltage range. These amplifiers include a precision op-amp with Over-The-Top® protected inputs that allow robust operation in environments with unpredictable conditions. The LT6375 amplifiers feature good common mode rejection ratio (CMRR), low gain error, highly-matched thin film resistor, and low gain drift. Typical applications include industrial data-acquisition front-ends, precision difference amplifiers, a replacement for isolation circuits, and high-voltage to low-voltage translation.
