I can't understand IIC address。
I use AD5121.
I don't know the meaning of the above two pictures
Here's what I wrote.
Hi,I moved your question to its proper community Precision DACs.Regards,
ADDR0 and ADDR1 are physical pins (check pin description section of the data sheet).
The combination of the logic states of these 2 pins will define the "device address" i2c frame you need to send to the device.
For example, if both pins are logic state = LOW, then you need to send 0101111 as your address.
Do you get ACK from the device? If yes then you are doing the right thing.
If vlogic=5v ， DIS=3.3V。 Can I set the chip to IIC mode?
I can not get ACK form the device。
