ADS1146IPWR from Texas Instruments, in a TSSOP-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; connect a 0.1-µF capacitor to DGND |
| 2 | DGND | power_in | Digital ground |
| 3 | CLK | input | External clock input; tie to DGND to activate the internal oscillator |
| 4 | RESET | input | Reset (active low) |
| 5 | REFP | input | Positive external reference input |
| 6 | REFN | input | Negative external reference input |
| 7 | AINP | input | Positive analog input |
| 8 | AINN | input | Negative analog input |
| 9 | AVSS | power_in | Negative analog power supply |
| 10 | AVDD | power_in | Positive analog power supply; connect a 0.1-µF capacitor to AVSS |
| 11 | START | input | Conversion start |
| 12 | CS | input | Chip select (active low) |
| 13 | DRDY | output | Data ready (active low) |
| 14 | DOUT/DRDY | tri_state | Serial data output or data out combined with data ready; enters high-impedance state when CS is high |
| 15 | DIN | input | Serial data input |
| 16 | SCLK | input | Serial clock input |
