高或低侧测量 High- or Low-Side Measurement

DESCRIPON

The INA230 is a current-shunt and power monitor with an I2C interface that features 16 programmable

addresses. The INA230 monitors both shunt voltage drops and bus supply voltage. Programmable

calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct

readouts of current in amperes and power in watts.
