The 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 LT6375 to existing difference amplifiers with high common mode voltage range, the selectable resistor divider ratios of the LT6375 offer superior system performance by allowing the user to achieve maximum SNR, precision and speed for a specific input common mode voltage range.

The op amp at the core of the LT6375 has Over-The-Top® protected inputs which allow for robust operation in environments with unpredictable voltage conditions. See the Applications Information section for more details.

The LT6375 is specified over the –40°C to 125°C temperature range and is available in space-saving MSOP16 and DFN14 packages.

Applications

  • High Side or Low Side Current Sensing
  • Bidirectional Wide Common Mode Range Current Sensing

Product Detail

Demonstration Circuit 2443 is a Configurable High Voltage Amplifier featuring the LT6375.


This demo board translates a high common mode signal to an output related to a low voltage reference level. The demo circuit is equipped with jumpers to facilitate setting the pin-strapped internal divider ratio configuration. The LT6375 is unique in that it may be powered from a low voltage (down to 3.3V) while it accepts signals well outside the supply range.
