INA219AIDR Description

INA219AIDR is a current shunt and power monitor with ANC or SMBUS compatible interface. The device monitors the shunt voltage drop and bus power supply voltage and has programmable conversion time and filtering functions. The programmable calibration value is combined with the internal multiplier to directly read the current (in amperes) and the additional multiplication registers to calculate power (in watts). The 2C or SMBus compatible interface has 16 programmable addresses.

There are two levels of NA219: an and B. Class B version has higher accuracy and higher precision specifications.

The INA219AIDR can be sensed on the shunt on the bus, ranging from 0 to 26. The device uses a single 3 to 26 shunts 5.5V power supply, maximum absorption of 1 mA of power supply current. The operating temperature of the INA219 ranges from-40 °C to 125 °C.
