Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN+ | power_in | Positive differential analog input pin; absolute voltage range is VSS-0.3V to VDD+0.3V and differential input should not exceed VREF/PGA. |
| 2 | VSS | power_in | Ground pin and current return path of the device, to be connected to a ground plane (analog ground if available) through a low impedance connection. |
| 3 | SCL | input | Serial clock input of the I2C interface (slave only, open-drain N-channel driver) that needs a pull-up resistor from VDD. |
| 4 | SDA | bidirectional | Bidirectional serial data pin of the I2C interface (open-drain N-channel driver) that needs a pull-up resistor from VDD. |
| 5 | VDD | power_in | Positive supply pin, 2.7V to 5.5V for specified operation, with about 0.1 µF ceramic bypass to ground and an additional 10 µF tantalum recommended. |
| 6 | VIN- | power_in | Negative differential analog input pin; absolute voltage range is VSS-0.3V to VDD+0.3V and differential input should not exceed VREF/PGA. |
