ADS1119IRTER

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

ADS1119IRTER 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 Reset input, active low; digital input voltage must stay between DGND and DVDD, and the pin should be tied to DVDD if unused.
2 DGND power_in Digital ground; AGND to DGND must be within -0.1 V to 0.1 V.
3 AGND power_in Negative analog power supply; connect to the thermal pad.
4 AIN3 input Analog input 3; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V.
5 AIN2 input Analog input 2; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V.
6 REFN input Negative reference input; absolute negative reference voltage must be between AGND - 0.1 V and V(REFP) - 0.75 V.
7 REFP input Positive reference input; absolute positive reference voltage 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.
9 AIN0 input Analog input 0; absolute input voltage must stay between AGND - 0.1 V and AVDD + 0.1 V.
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 Data ready output, active low and open-drain; connect to DVDD using a pullup resistor.
13 SDA bidirectional I2C serial data input and output; connect to DVDD using a pullup resistor.
14 SCL input I2C serial clock input; connect to DVDD using a pullup resistor.
15 A0 input I2C slave address select pin 0; can be tied to DGND, DVDD, SDA or SCL.
16 A1 input I2C slave address select pin 1; can be tied to DGND, DVDD, SDA or SCL, giving 16 possible addresses together with A0.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
