Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCLK | input | Serial clock input for the serial interface, used to clock data on DIN and DOUT/RDY. |
| 2 | CLK | bidirectional | Master clock pin for the device, used with an external clock source or a crystal connection. |
| 3 | CS | input | Chip select input that enables communication with the serial interface. |
| 4 | IOUT1 | output | Excitation current source output 1 for resistive/RTD sensor bridge excitation, selectable at 10 µA, 210 µA or 1 mA. |
| 5 | AIN1(+) | input | Positive analog input of differential channel AIN1, paired with AIN1(-). |
| 6 | AIN1(-) | input | Negative analog input of differential channel AIN1, paired with AIN1(+). |
| 7 | AIN2(+) | input | Positive analog input of differential channel AIN2, paired with AIN2(-). |
| 8 | AIN2(-) | input | Negative analog input of differential channel AIN2, paired with AIN2(+). |
| 9 | REFIN(+)/AIN3(+) | input | Positive external reference input (REFIN(+)) which must be kept between GND + 0.1 V and AVDD, or positive input of AIN3 when used as an analog input. |
| 10 | REFIN(−)/AIN3(−) | input | Negative external reference input (REFIN(-)) which must be kept between GND and AVDD - 0.1 V, or negative input of AIN3 when used as an analog input. |
| 11 | IOUT2 | output | Excitation current source output 2 for resistive/RTD sensor bridge excitation, selectable at 10 µA, 210 µA or 1 mA. |
| 12 | GND | power_in | Ground reference point for the analog and digital circuitry. |
| 13 | AVDD | power_in | Analog supply voltage, specified from 2.7 V to 5.25 V. |
| 14 | DVDD | power_in | Digital supply voltage, specified from 2.7 V to 5.25 V, and may be set independently of AVDD. |
| 15 | DOUT/RDY | output | Serial data output that also serves as the data ready indicator, going low when a conversion result is available. |
| 16 | DIN | input | Serial data input for writing to the on-chip mode, configuration and register set. |
