Hello,

Each transmission consists of a START condition sent by a master, followed by the AD7414 7-bit slave address plus R/W bit, a register address byte, one or more data bytes, and finally a STOP condition.

With respect to the device address, please refer to the following table:

In case you are using the device address 0x94 means that you have part number AD4114-0 and the AS pin connected to VDD (it is recommended a pull resistor of 1 kΩ). Please be aware about this information.

Besides, make sure you have the corresponding pull-up resistors at the SDA and SCL lines.

I hope this information will be useful for you.

If I misunderstood your question, feel free to let me know. I will be glad to help.

Have a great day.

David Diaz.
