ADS1115BQDGSRQ1

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

ADS1115BQDGSRQ1 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 input, state sampled continuously.
2 ALERT/RDY tri_state Open-drain comparator output or conversion-ready digital output, requires pullup resistor to VDD.
3 GND power_in Analog ground reference.
4 AIN0 input Analog input 0, accepts voltages from GND − 0.3 V to VDD + 0.3 V.
5 AIN1 input Analog input 1, accepts voltages from GND − 0.3 V to VDD + 0.3 V.
6 AIN2 input Analog input 2, accepts voltages from GND − 0.3 V to VDD + 0.3 V.
7 AIN3 input Analog input 3, accepts voltages from GND − 0.3 V to VDD + 0.3 V.
8 VDD power_in Analog power supply, 2.0 V to 5.5 V with 0.1 μF bypass capacitor to GND required.
9 SDA bidirectional I2C serial data bidirectional open-drain input/output, requires pullup resistor to VDD.
10 SCL input I2C serial clock input, requires pullup resistor to VDD.
