onsemi NCx211R Current Sense Amplifiers

onsemi NCx211R Current Sense Amplifiers are voltage output current-shunt monitors with zero-drift architecture that enable low or high-side current sensing. These current sense amplifiers can measure the voltage across shunts at common-mode voltages from -0.3V to 26V. The NCx211R current sense amplifiers operate from a single 2.2V to 26V power supply and draw a maximum 80μA of supply current. Typical applications include current sensing, automotive, telecom, power management, battery charging, and discharging.
