INA220: About INA220 address latching

Part Number: INA220

hi dear supporting team,

for INA220 Address latching, will it be identify on powering up or over every time I2C communication lauching? ii.e if after power up, we change the address, will it be identified ? tks a lot!

  • Hello Vera,

    According to section of the datasheet, the address pins are sampled at the start of each communication event. Changing the connection of the address pins after power up is no problem, they just need to be at the desired value before the next communication begins.
