Product Introduction

The INA219 is a high-side current shunt and C-mount power monitoring with I2. The INA219 shunts simultaneously monitor and supply voltage drops, with programmable changeover times and filtering. A programmable calibration value with internal multipliers combined to make the ampere direct reading. The other is multiplied by the registered watt power. 16 programmable addresses via I2C interface function.

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

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