Features:
ADS1115 can be controlled through I2C The chip is controlled by an I2C interface that provides 16-bit accuracy and a sampling rate of 3300 times/second. The chip can be configured as 4 single-ended input channels or 2 differential channels. In addition, it has a built-in programmable gain amplifier (up to 16 times) to amplify small single-ended/differential signals to the full range.
The chip is small, so it is mounted on a breakout board with a ferrite core to keep AVDD and AGND quiet and connected via an I2C interface.
Just connect GND to ground, VDD to logic power, and SCL/SDA to the I2C port of the microcontroller, then run the example code to start reading data.
