ADS1115 16-Bit ADC – 4 Channel with Programmable Gain Amplifier – STEMMA QT / Qwiic

Measure analog signals accurately with the ADS1115 16-Bit ADC.

Many microcontrollers have very basic or no analog inputs. However, this ADS1115 16-Bit ADC provides a professional solution. It offers 16-bit resolution over the I2C bus. Consequently, you get much smoother and more reliable data from your sensors.

Key Features:

• 16-Bit High Resolution: It features a very high level of detail. Because of this, it is perfect for precision weighing or light sensing.

• 4 Input Channels: The board includes four single-ended or two differential inputs. Therefore, you can monitor multiple sensors at the same time.

• STEMMA QT / Qwiic Compatible: It features a plug-and-play I2C interface. Furthermore, you can connect it without any soldering or messy wires.

• Programmable Gain Amplifier (PGA): It allows you to boost small signals up to 16x. Simply adjust the gain in your code for weak sensors.

Why should you buy this ADC module? Are you building a laboratory instrument or a Raspberry Pi project? Because of its wide voltage range, it works with 2V to 5V systems. Moreover, it is fully compatible with Arduino, CircuitPython, and Python libraries. Furthermore, it is very compact and easy to mount. Therefore, it is a must-have for any serious electronics maker. Simply connect it to your I2C pins to begin.
