The INA190-EP 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 INA190-EP is approximately 150 dB. The ability to reject changes in the DC common-mode voltage allows the INA190-EP to monitor both high- and low-voltage rail currents with very little change in the offset voltage.
