INA149 Description
The INA149 is a precision unity-gain difference amplifier with a very high input mon-mode voltage range. It is a single, monolithic device that consists of a precision op amp and an integrated thinfilm resistor network. The INA149 can accurately measure small differential voltages in the presence of mon-mode signals up to ±275.
