AD629BNZ

AD629 is a difference amplifier with a very high input, common-mode voltage range. It is a precision device that allows the user to accurately measure differential signals in the presence of high common-mode voltages upto ±270. It has low offset, low offset drift, low gain error drift, low common-mode rejection drift, and excellent CMRR over a wide frequency range. It is widely used in application such as high voltage current sensing, battery cell voltage monitors, power supply current monitors, motor controls, isolation etc.
