Hi all,
How many INA3221 is it possible to connect on the same I2C bus ?
Because it is possible depending on the wiring to have 4 different addresses : 0x40x, 0x41, 0x42 and 0x43.
Normally with I2C bus, the address is on 7 bits and the last one is to notify if it is for R/W correct ?
So the maximum of INA3221 on a same I2C bus is two ?
Thank you,
Thank you for posting on the E2E Forums,
Its possible to have up to four devices on the same bus, assuming there are no other devices already present on the bus that use the same addresses.
All four addressing combinations are <128 and can therefore be represented by a 7 bit binary number, which is shifted left to accommodate the MSB positions, as per figure 27, on the device datasheet. The last bit indicates a R/W condition.
