Dear ADI experts,
I'm using the ADAU1701 in a circuit where there are multiple devices on the I2C bus. I'd like to be able to power down the ADAU1701, and then let a master I2C device talk to some other devices on the I2C bus. In this scheme of things the I2C bus voltages would hit the ADAU1701 pins and there would be no voltages applied to any other pins of the chip. Is that OK? More specifically, a) will the SCL and SDA pins be in a high impedance state? and b) is there risk of damage to the chip?
Thanks - Ram
