High Common-Mode Rejection

The INA186 uses a capacitively coupled amplifier on the front end. Therefore, dc common-mode voltages are blocked from downstream circuits, resulting in very high common-mode rejection. Typically, the common-mode rejection of the INA186 is approximately 150 dB. The ability to reject changes in the dc common-mode voltage allows the INA186 to monitor both high-voltage and low-voltage rail currents with very little change in the offset voltage.
