The INA228AIDGSR is an ultra-precision digital power monitor with a 20-bit Δ-sigma ADC designed for current-sense applications that measures ±163.84mV or ±40.96mV full-scale differential inputs across a resistive shunt sense element with common mode voltage support ranging from -0.3V to +85V.
The INA228 reports current, bus voltage, temperature power, energy, and charge accumulation with an integrated oscillator with ±0.5% accuracy while performing the required calculations in the background. An integrated temperature sensor is used for die temperature measurement with ±1°C accuracy and can be used to monitor the system ambient temperature.
