ADS1219IRTET

Texas Instruments · Analog To Digital Converters (ADC) · WQFN-16-EP(3x3)

ADS1219IRTET 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 device reset; the RESET input is limited to DGND to DVDD, with VIH of 0.7·DVDD minimum, and must be tied to DVDD if unused.
2 DGND power_in Digital ground for the DVDD supply, which must be decoupled with a 100-nF or larger capacitor to DGND.
3 AGND power_in Negative analog power supply; AVDD to AGND is specified at 2.3 V to 5.5 V and AGND to DGND at -0.1 V to 0.1 V.
4 AIN3 input Analog input 3; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V for gain of 1 and 4.
5 AIN2 input Analog input 2; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V for gain of 1 and 4.
6 REFN input Negative reference input; V(REFN) must be between AGND - 0.1 V and V(REFP) - 0.75 V.
7 REFP input Positive reference input; V(REFP) must be between V(REFN) + 0.75 V and AVDD + 0.1 V.
8 AIN1 input Analog input 1; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V for gain of 1 and 4.
9 AIN0 input Analog input 0; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V for gain of 1 and 4.
10 AVDD power_in Positive analog power supply, specified at 2.3 V to 5.5 V; connect a 100-nF (or larger) capacitor to AGND.
11 DVDD power_in Positive digital power supply, specified at 2.3 V to 5.5 V; connect a 100-nF (or larger) capacitor to DGND.
12 DRDY output Open-drain data-ready output, active low; connect to DVDD using a pullup resistor and absolute digital input limit is DGND - 0.3 V to 7 V.
13 SDA bidirectional Serial data input and output for the I2C bus; connect to DVDD using a pullup resistor.
14 SCL input Serial clock input for the I2C bus; connect to DVDD using a pullup resistor.
15 A0 input I2C slave address select pin 0, which can be tied to DGND, DVDD, SDA, or SCL to select one of 16 addresses.
16 A1 input I2C slave address select pin 1, which can be tied to DGND, DVDD, SDA, or SCL to select one of 16 addresses.
17 Thermal pad passive Exposed thermal power pad that must be connected to AGND and soldered to the PCB for thermal and mechanical performance.
