I am designing an audio product that uses I2C with the TCA9548A I2C switch.
I am running the audio circuitry from split supplies, +2.5v and -2.5v in order to eliminate 256 coupling capacitors that would be needed if I ran the audio off a single 5v supply.
The TCA9548A is also powered by the +2.5v and -2.5v supply.
The microprocessor that generates the I2C for the TCA9548A MUST run off 5v.
This means that I need a means to shift the 0v/5V I2C signals from the microprocessor to -2.5v/ 2.5v for the TCA9548A.
Can anyone please recommend a part that will accomplish that?
Thanks,
Lukas
