Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DVDD | power_in | Digital power supply; connect to 2.7V to 5.3V |
| 2 | DGND | power_in | Digital ground reference |
| 3 | CLKIN/XTAL1 | input | External clock input or crystal oscillator pin 1; tie low to activate internal oscillator |
| 4 | XTAL2 | passive | Crystal oscillator pin 2; leave disconnected if using external clock or internal oscillator |
| 5 | DGND | power_in | Digital ground reference |
| 6 | DGND | power_in | Digital ground reference |
| 7 | TEMP | input | Temperature sensor select input; high selects internal temperature sensor, low selects analog input channels |
| 8 | A0 | input | Analog input channel select pin; used with TEMP to multiplex between analog inputs |
| 9 | CAP | passive | PGA bypass capacitor pin 1; connect 0.1µF capacitor to pin 10 to create 720Hz low-pass filter |
| 10 | CAP | passive | PGA bypass capacitor pin 2; connect 0.1µF capacitor to pin 9 to create 720Hz low-pass filter |
| 11 | AINP1 | input | Positive differential input for channel 1 |
| 12 | AINN1 | input | Negative differential input for channel 1 |
| 13 | AINN2 | input | Negative differential input for channel 2 |
| 14 | AINP2 | input | Positive differential input for channel 2 |
| 15 | REFN | input | Negative voltage reference input; range AGND - 0.1V to (REFP - 1.5V) |
| 16 | REFP | input | Positive voltage reference input; range (REFN + 1.5V) to (AVDD + 0.1V) |
| 17 | AGND | power_in | Analog ground reference |
| 18 | AVDD | power_in | Analog power supply; connect to 2.7V to 5.3V |
| 19 | GAIN0 | input | Gain select input bit 0 (LSB); used with GAIN1 to set gain of 1, 2, 64, or 128 |
| 20 | GAIN1 | input | Gain select input bit 1 (MSB); used with GAIN0 to set gain of 1, 2, 64, or 128 |
| 21 | SPEED | input | Data rate select input; low selects 10SPS with 50/60Hz rejection, high selects 80SPS |
| 22 | PDWN | input | Power-down control input; hold low to power down and reset ADC; toggle high then low at startup |
| 23 | SCLK | input | Serial clock input; data shifted out on rising edges with rise/fall times less than 50ns required |
| 24 | DRDY/DOUT | output | Dual-function digital output; goes low when data ready, then outputs 24-bit result MSB first on SCLK rising edges |
