Other Parts Discussed in Thread: INA226
Hi -
On the INA228, when selecting a Secondary Device Address for I2C such that A0 or A1 is connected to SDA or SCL pin, should this be directly connected to the SDA/SCL pin or should it be attached through a resistor?
Given that SDA and SCL are I2C bus pins and common to every other device on the I2C interface, I just want to make sure that there are no other drawbacks to selecting addresses that require the A0/A1 connection to SDA/SCL.
A follow-up question is whether using the A0/A1 connection to SDA/SCL adds to the capacitive load seen by the I2C bus because A0 or A1 are also theoretically connected to the bus in addition to the SDA/SCL pins?
Thanks,
Tom
