TPA2016D2: Changing device i2c address to accommodate two same devices in the design

Goran Jurkovic

Part Number: TPA2016D2

Tool/software:

I have a pcb design with two TPA2016D2 devices on board. Having separate i2c busses is not an option here. I only have one i2c bus.

PDF clearly states that the i2c address can be changed, but it doesn't say how.

So, how to change one's address to accommodate two devices?

Hey Goran,

Below are images I retrieved from the EVM's User Guide. You can retrieve the i2c address info from here.

Regards,

Ore.

The tpa2016d2s are soldered on the pcb. There is stm32 arm connected to them. I cannot connect them to pc to use that program.

I need i2c instructions in what register to change the address (1 to 7).

Thanks.
