Description
The INA149 is a precision unity-gain difference amplifier with a very high input common-mode voltage range. It is a single, monolithic device that consists of a precision op amp and an integrated thin film resistor network.
The device can accurately measure small differential voltages in the presence of common-mode signals up to ±275 V. The IC inputs are protected from momentary common-mode or differential overloads of up to 500 V.
