## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREF | power_in | Reference input for ADC; voltage range 0.5 V to VCC |
| 2 | +In | input | Noninverting analog input; voltage range GND - 0.1 V to VCC + 0.1 V |
| 3 | -In | input | Inverting analog input for differential measurement; voltage range GND - 0.1 V to 1 V; connect to ground or remote ground sense point |
| 4 | GND | power_in | Ground; 0 V reference |
| 5 | CS/SHDN | input | Chip select (active LOW); shutdown mode when HIGH; digital input accepts 3 V to 5.5 V logic levels |
| 6 | DOUT | output | Serial output data; 16 bits MSB first; data valid on DCLOCK falling edge |
| 7 | DCLOCK | input | Data clock input synchronizes serial data transfer; frequency range 0.024 MHz to 2.4 MHz |
| 8 | +VCC | power_in | Power supply; voltage range 2.7 V to 5.25 V (specified operating range) |
