TI INA212CQDCKRQ1

The INA21x-Q1 series are voltage-output current shunt monitors (also known as current sense amplifiers) that sense the voltage drop across a shunt resistor at common-mode voltages ranging from -0.3V to 26V, independent of the supply voltage. Five fixed gains are available: 50V/V, 75V/V, 100V/V, 200V/V, 500V/V, and 1000V/V. These devices are commonly used for overcurrent detection, voltage feedback control loops, or as power monitors. The low offset of the zero-drift architecture enables current sensing with a maximum voltage drop across the shunt as low as 10mV (full scale). These devices operate from a single 2.7V to 26V supply and consume a maximum supply current of 100μA. They are rated for an operating temperature range of -40°C to +125°C and are available in a 6-pin SC70 package.
