how to communicate with SGTL5000

Question asked by Jeremy Martin on May 9, 2018

I would like used the SGTL5000 but i don't understand how to communicate with him. I work with the 20 pins module, I put Vdda & Vddio to 3.3V and pin 21 to GND. 

I try to write an register with the I2C bus but i don't find the SGTL5000 at address 0x0A like it's say in datasheet.
