Pin Configuration
| Pin | Name | Description |
|---|---|---|
| 1 | ADDR | I2C Address pin. This pin must be connected to IO_VDD or GND to determine the I2C Device Address. |
| 2 | SDA | I2C Serial Data |
| 3 | IO_VDD | The power supply input for the digital communication bus. Optionally decouple this pin to ground with a 0.1uF ceramic capacitor. (Internally tied to Pin 11) |
| 4 | RES | Reserved. Connect to GND. Optionally, can be connected to IO_VDD or VDD. Do not leave floating. |
| 5 | INT | Physical Interrupt pin (Push-Pull). Leave floating if not used. |
| 6 | GND | Ground. (Internally tied to Pins 8, 9) |
| 7 | VDD | The power supply input. Decouple this pin to ground with a 0.1uF ceramic capacitor. (Internally tied to Pin 10) |
| 8 | GND | Ground. (Internally tied to Pins 6, 9) |
| 9 | GND | Ground. (Internally tied to Pins 6, 8) |
| 10 | VDD | The power supply input. Decouple this pin to ground with a 0.1uF ceramic capacitor. (Internally tied to Pin 7) |
| 11 | IO_VDD | The power supply input for the digital communication bus. Optionally decouple this pin to ground with a 0.1uF ceramic capacitor. (Internally tied to Pin 3) |
