Slave Address
The MAX5392 includes a 7-bit slave address (Figure 4).
The 8th bit following the 7th bit of the slave address is the
NOP/W bit. Set the NOP/W bit low for a write command
and high for a no-operation command. The device does
not support readback.
The device provides three address inputs (A0, A1, and
A2), allowing up to eight devices to share a common
bus (Table 1). The first 4 bits (MSBs) of the factory-set
slave addresses are always 0101. A2, A1, and A0 set the
next 3 bits of the slave address. Connect each address
input to VDD or GND. Each device must have a unique
address to share a common bus.
Message Format for Writing
Write to the devices by transmitting the device’s slave
address with NOP/W (8th bit) set to zero, followed by
at least 2 bytes of information. The first byte of informa-
tion is the command byte. The second byte is the data
byte. The data byte goes into the internal register of the
device as selected by the command byte (Figure 7 and
Table 2).
