The MAX11041 includes a 7-bit slave address. The first
5 bits (MSBs) of the slave address are factory-pro-
grammed and always 01000. The logic state of the
address inputs (A1 and A0) determine the last two
LSBs of the device address (see Figure 6). Connect A1
and A0 to V
mum of four MAX11041 devices can be connected on
the same bus at one time using these address inputs.
The 8th bit of the address byte is a read/write bit (R/W).
If this bit is set to 0, the device expects to receive data.
If this bit is set to 1, the device expects to send data.
