4 channel analog/digital converter with I2C interface

Model: ADS1115.
ADS1115 is an analog-to-digital converter module with a 16-bit resolution. It is a low-power device and operates at a voltage range of 2.0-5.5 V. The ADS1115 IC oscillator and communicated to a microcontroller using the I2C communication protocol. It also includes a programmable gain amplifier up to x16, which helps to scale up small/differential signals to the full range.
