The INA183 is a 2.7V to 26V Precision Current Sense Amplifier
The INA183 is a high precision voltage output, AD630BD shunt monitor (also known as a current sense amplifier) typically used for overcurrent protection, precision current measurement for system optimization, or closed-loop feedback circuits. The device can sense the voltage drop across the shunt resistor at common-mode voltages from 2.7 V to 26 V. Three fixed gains are available: 50 V/V, 100 V/V, and 200 V/V. The low offset of the zero-drift architecture supports current sensing with a maximum voltage drop across the shunt down to 10mV full scale.
The device operates by drawing power from the IN+ pin with a maximum supply current of 130µA. All versions are rated from –40 °C to 125 °C and are available in a 5-pin SOT-23 package.
