Analog Devices Inc. LT6376 Voltage Difference Amplifiers
Analog Devices Inc. LT6376 Voltage Difference Amplifiers have a gain of 10 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 LT6376 amplifiers feature good Common Mode Rejection Ratio (CMRR), low gain error, highly-matched thin film resistor, and low gain drift. Typical applications include high-side or low side current sensing, precision difference amplifiers, a replacement for isolation circuits, and high-voltage to low-voltage translation.
