PRODUCTION DATA.
The I2C address for the device is determined by connecting external resistors on the ADDR pin. The device address is determined at power-up based on the resistor values. The device retains this address until the next power-up event, until the next device reset, or until the device receives a command to program its own address. Figure 23 shows a connection diagram for the ADDR pin and Table 5 lists the resistor values for selecting different addresses of the device.
