INA210AIRSWT

The INA21x are voltage output, shunt monitors (also known as current sense amplifiers). These devices typically provide overcurrent protection and precision current measurement for system optimization, and are also commonly used in closed-loop feedback circuits. This family of devices senses the voltage drop across a shunt resistor over a common-mode voltage range of –0.3V to 26V, independent of the supply voltage. Six fixed gains are available: 50V/V, 75V/V, 100V/V, 200V/V, 500V/V, or 1000V/V. The devices employ a zero-drift architecture with low offset, enabling current sensing with a maximum full-scale voltage drop across the shunt resistor of less than 10mV. The devices operate from a single supply voltage of 2.7V to 26V with a maximum supply current of 100μA. All device versions are rated for operation over an extended operating temperature range of -40°C to +125°C, available in SC70 and UQFN packages.
