PRODUCTION DATA
The I2C address for the device is determined by connecting external resistors on the ADDR pin. The device address is selected on power-up based on the resistor values. The device retains this address until the next power up, until the next device reset, or until the device receives a command to program the address (Section 7.3.10.3). Figure 7-7 provides the connection diagram for the ADDR pin and Table 7-2 provides the resistor values for selecting a different addresses of the device.
