ADS1231ID from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DVDD | power_in | Digital power supply. |
| 2 | GND | power_in | Ground for digital and analog supplies. |
| 3 | CLKIN | input | External clock input: typically 4.9152MHz; tie low to activate internal oscillator. |
| 4 | SPEED | input | Data rate select: 0 = 10SPS, 1 = 80SPS. |
| 5 | CAP | passive | Gain amplifier bypass capacitor connection. |
| 6 | CAP | passive | Gain amplifier bypass capacitor connection. |
| 7 | AINP | input | Positive analog input. |
| 8 | AINN | input | Negative analog input. |
| 9 | VREFN | input | Negative reference input. |
| 10 | VREFP | input | Positive reference input. |
| 11 | GND | power_in | Ground for digital and analog supplies. |
| 12 | SW | output | Low-side power switch. |
| 13 | AVDD | power_in | Analog power supply. |
| 14 | PDWN | input | Power-down: holding this pin low powers down the entire converter and resets the ADC. |
| 15 | SCLK | input | Serial clock: clock out data on the rising edge; also used to initiate Standby mode. |
| 16 | DRDY/DOUT | output | Dual-purpose output: data ready indicates valid data by going low; data output outputs data, MSB first, on the first rising edge of SCLK. |
