ADI LT6376HMS#PBF

The LT6376 is a gain of 10 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 LT6376 to existing difference amplifiers with high common mode voltage range, the gain of 10 and selectable resistor divider ratios of the LT6376 offer superior system performance by allowing the user to achieve low input referred noise with maximum precision and speed.

The op amp at the core of the LT6376 has Over-The-top protected inputs which allow for robust operation in environments with unpredictable voltage conditions.

The LT6376 is specified over the -40°C to 125°C temperature range and is available in space-saving MSOP16 and DFN14 packages.
