INA219BIDR Description

The INA219 is a current shunt and power monitor with an I2C- or SMBus-compatible interface. The device monitors both shunt voltage drop and bus supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts of current in amperes. An additional multiplying register calculates power in watts. The I2C- or SMBus-compatible interface features 16 programmable addresses.
