ADS1219IRTER from Texas Instruments, in a WQFN-16-EP(3x3). 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 | RESET | input | Active-low reset input; the datasheet specifies a recommended input range of DGND to DVDD, and it should be tied to DVDD if not used. |
| 2 | DGND | power_in | Digital ground, with DGND to AGND limited to -0.1 V to 0.1 V under recommended operating conditions. |
| 3 | AGND | power_in | Negative analog power supply, which is the analog ground reference for AVDD (AVDD to AGND recommended 2.3 V to 5.5 V). |
| 4 | AIN3 | input | Analog input 3, with absolute input voltage limited to AGND - 0.1 V to AVDD + 0.1 V for gain 1 and gain 4. |
| 5 | AIN2 | input | Analog input 2, with absolute input voltage limited to AGND - 0.1 V to AVDD + 0.1 V for gain 1 and gain 4. |
| 6 | REFN | input | Negative reference input, with absolute voltage limited to AGND - 0.1 V to V(REFP) - 0.75 V. |
| 7 | REFP | input | Positive reference input, with absolute voltage limited to V(REFN) + 0.75 V to AVDD + 0.1 V. |
| 8 | AIN1 | input | Analog input 1, with absolute input voltage limited to AGND - 0.1 V to AVDD + 0.1 V for gain 1 and gain 4. |
| 9 | AIN0 | input | Analog input 0, with absolute input voltage limited to AGND - 0.1 V to AVDD + 0.1 V for gain 1 and gain 4. |
| 10 | AVDD | power_in | Positive analog power supply, 2.3 V to 5.5 V relative to AGND; connect a 100-nF (or larger) capacitor to AGND. |
| 11 | DVDD | power_in | Positive digital power supply, 2.3 V to 5.5 V relative to DGND; connect a 100-nF (or larger) capacitor to DGND. |
| 12 | DRDY | output | Active-low, open-drain data-ready output that must be connected to DVDD through a pullup resistor. |
| 13 | SDA | bidirectional | Serial data input and output for the I2C interface, which must be connected to DVDD through a pullup resistor. |
| 14 | SCL | input | Serial clock input for the I2C interface, which must be connected to DVDD through a pullup resistor; digital input range is DGND to 5.5 V when DVDD is 3.0 V to 5.5 V. |
| 15 | A0 | input | I2C slave address select pin 0, tied to DGND, DVDD, SDA, or SCL; digital input range is DGND to DVDD + 0.5 V for DVDD 2.3 V to 3.0 V and DGND to 5.5 V for DVDD 3.0 V to 5.5 V. |
| 16 | A1 | input | I2C slave address select pin 1, tied to DGND, DVDD, SDA, or SCL; digital input range is DGND to DVDD + 0.5 V for DVDD 2.3 V to 3.0 V and DGND to 5.5 V for DVDD 3.0 V to 5.5 V. |
| 17 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
