INA219BIDCNT Description

The INA219BIDCNT 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.
The INA219BIDCNT is available in two grades: A and B. The B grade version has higher accuracy and higher precision specifications.
