ADS1219IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A0 | input | I2C slave address select pin 0 for device address configuration. |
| 2 | A1 | input | I2C slave address select pin 1 for device address configuration. |
| 3 | RESET | input | Reset input active low, minimum pulse width 250 ns required. |
| 4 | DGND | power_in | Digital ground reference. |
| 5 | AGND | power_in | Analog ground reference. |
| 6 | AIN3 | input | Analog input 3, voltage range AGND - 0.1 V to AVDD + 0.1 V. |
| 7 | AIN2 | input | Analog input 2, voltage range AGND - 0.1 V to AVDD + 0.1 V. |
| 8 | REFN | input | Negative external reference input, voltage range AGND - 0.1 V to REFP - 0.75 V. |
| 9 | REFP | input | Positive external reference input, voltage range REFN + 0.75 V to AVDD + 0.1 V. |
| 10 | AIN1 | input | Analog input 1, voltage range AGND - 0.1 V to AVDD + 0.1 V. |
| 11 | AIN0 | input | Analog input 0, voltage range AGND - 0.1 V to AVDD + 0.1 V. |
| 12 | AVDD | power_in | Positive analog power supply 2.3 V to 5.5 V, requires 100 nF bypass capacitor to AGND. |
| 13 | DVDD | power_in | Positive digital power supply 2.3 V to 5.5 V, requires 100 nF bypass capacitor to DGND. |
| 14 | DRDY | output | Data ready output active low, open-drain indicating new conversion result ready. |
| 15 | SDA | bidirectional | I2C serial data line open-drain bidirectional, requires pullup resistor to DVDD. |
| 16 | SCL | input | I2C serial clock input open-drain capable, requires pullup resistor to DVDD. |
