It senses voltage drops across current-shunt resistors at common-mode voltages from 0 V to 36 V, independent of the supply voltage. Two gain-select pins (GS0, GS1) program four discrete gain levels of 25, 50, 100, and 200 V\/V. The zero-drift architecture provides \u00b1150 \u00b5V maximum offset voltage and 0.5 \u00b5V\/\u00b0C drift, enabling high-precision measurement over the full automotive temperature range.","working_principle":"The INA225-Q1 uses a zero-drift (chopper-stabilized) architecture to achieve ultra-low offset voltage and drift. The differential voltage across the shunt resistor is amplified by the selected gain (set by GS0\/GS1 pins) and referenced to the voltage at the REF pin. For bidirectional measurement, the REF pin is connected to a reference voltage (e.g., VS\/2), allowing the output to indicate both current directions. The auto-zeroing cycle continuously cancels input offset, maintaining precision over temperature and time.","pin_description":"
