AIN7/GPIO7 | 6 | AI, DI, DO | Channel 7; configurable as either an analog input (default) or a GPIO |
ADDR | 11 | AI | Input for selecting the device I2C address.
Connect a resistor to this pin from DECAP pin or GND to select one of the eight addresses. |
ALERT | 12 | Digital output | Open-drain (default) or push-pull output for the digital comparator |
AVDD | 7 | Supply | Analog supply input, also used as the reference voltage to the ADC; connect a 1-µF decoupling capacitor to GND |
DECAP | 8 | Supply | Connect a1-µF decoupling capacitor between the DECAP and GND pins for the internal power supply |
DVDD | 10 | Supply | Digital I/O supply voltage; connect a 1-µF decoupling capacitor to GND |
GND | 9 | Supply | Ground for the power supply; all analog and digital signals are referred to this pin voltage |
SDA | 14 | DI, DO | Serial data input or output for the I2C interface |
SCL | 13 | DI | Serial clock for the I2C interface |
Thermal pad | — | Supply | Exposed thermal pad; connect to GND. |
