ADS1114IDGST

Texas Instruments · Analog To Digital Converters (ADC) · VSSOP-10-0.5mm

ADS1114IDGST from Texas Instruments, in a VSSOP-10-0.5mm. 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 ADDR input I2C target address select pin; connect to GND, VDD, SDA, or SCL to select one of four addresses, and its state is sampled continuously.
2 ALERT/RDY output Open-drain comparator output or conversion-ready output on the ADS1114; it requires a pullup resistor to VDD and can be left unconnected or tied to VDD through a weak pullup if unused.
3 GND power_in Analog ground and device reference; the power supply is specified as VDD to GND, and a 0.1 µF decoupling capacitor is recommended from VDD to GND.
4 AIN0 input Analog input 0; the absolute input voltage must stay between GND and VDD, the absolute maximum is GND - 0.3 V to VDD + 0.3 V, and negative voltages must not be applied.
5 AIN1 input Analog input 1; the absolute input voltage must stay between GND and VDD, the absolute maximum is GND - 0.3 V to VDD + 0.3 V, and negative voltages must not be applied.
6 NC unconnected No connect on the ADS1114 (AIN2 is only used on the ADS1115); leave floating or connect to GND.
7 NC unconnected No connect on the ADS1114 (AIN3 is only used on the ADS1115); leave floating or connect to GND.
8 VDD power_in Power supply, 2.0 V to 5.5 V relative to GND; connect a 0.1 µF decoupling capacitor to GND.
9 SDA bidirectional I2C serial data input/output, open-drain with a pullup resistor to VDD; the digital input absolute maximum is GND - 0.3 V to 5.5 V.
10 SCL input I2C serial clock input, open-drain bus line with a pullup resistor to VDD; the digital input absolute maximum is GND - 0.3 V to 5.5 V.
