# ADS1115IDGST

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

ADS1115IDGST 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; state sampled continuously; connect to GND, VDD, SDA, or SCL to select one of four device addresses. |
| 2 | ALERT/RDY | tri_state | Comparator output or conversion-ready signal (ADS1115 only); open-drain output; polarity and function configurable via Config register; connect to VDD with pullup resistor. |
| 3 | GND | power_in | Analog ground reference. |
| 4 | AIN0 | input | Analog input channel 0; accepts voltages from GND to VDD; absolute maximum voltage GND - 0.3V to VDD + 0.3V. |
| 5 | AIN1 | input | Analog input channel 1; accepts voltages from GND to VDD; absolute maximum voltage GND - 0.3V to VDD + 0.3V. |
| 6 | AIN2 | input | Analog input channel 2 (ADS1115 only); accepts voltages from GND to VDD; absolute maximum voltage GND - 0.3V to VDD + 0.3V. |
| 7 | AIN3 | input | Analog input channel 3 (ADS1115 only); accepts voltages from GND to VDD; absolute maximum voltage GND - 0.3V to VDD + 0.3V. |
| 8 | VDD | power_in | Analog power supply; operating voltage range 2.0V to 5.5V; requires 0.1μF bypass capacitor to GND; absolute maximum 7V. |
| 9 | SDA | bidirectional | I2C serial data line; open-drain bidirectional; connect to VDD with 1kΩ to 10kΩ pullup resistor; device pulls low for data transmission. |
| 10 | SCL | input | I2C serial clock input; connect to VDD with 1kΩ to 10kΩ pullup resistor; device does not drive this line low; supports standard (100kHz), fast (400kHz), and high-speed (3.4MHz) modes. |
