DESCRIPTION
The
LT
®
6375
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 envi-
ronments with unpredictable voltage conditions. See the
Applications Information section for more details.
The LT6375 is specified over the –40°C to 125°C tem-
perature range and is available in space-saving MSOP16
and DFN14 packages.
