Product introduction

The INA219 is a high-side current shunt and C-interface power supply monitoring with I^2。 The INA219 shunts simultaneous monitoring and supply voltage drops with programmable conversion time and filtering. A programmable calibration value, combined with an internal multiplier, enables direct reading in amperes. The other multiplied by the register is calculated in watt power. Through I²C interface function, 16 programmable addresses.

The INA219 is available in two grades: A and B grade B versions with higher accuracy and higher accuracy specifications.

The feeling of the INA219 shunted on the bus can be changed from 0V to 26V. The device operates from a single +3 V to +5.5 V supply, drawing a maximum supply current of 1 mA. The INA219 operates from -40°C to +125°C
