INA219AIDCNR

The INA219AIDCNR is a high-side Current Shunt and Power Monitor with an I?C interface. The INA219AIDCNR monitors both shunt drop and supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The I?C interface features 16 programmable addresses. The INA219 is available in two grades: A and B. The B grade version has higher accuracy and higher precision specifications. The INA219AIDCNR senses across shunts on buses that can vary from 0 to 26V. The device uses a single +3 to +5.5V supply, drawing a maximum of 1mA of supply current.
