This is a programmable gain amplifier with ADS1115 16-bit ADC of 4 channels. ADS1115 module is Raspberry Pi and microcontrollers without an Analog-to-digital converter. When you want a higher-precision ADC, this ADS1115 provides 16-bit precision at 860 samples/ second over I2C.
This module can be configured as 4 single-end input channels or two differential channels. This included a programmable gain amplifier up to x16 to help boost up a smaller single/differential signals to the full range. This ADC can run from 2V to 5V power/logic. It can measure a large range of signals and its super easy to use. This module is a 16-bit general-purpose converter.
This chip fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Its interfacing is done through I2C. the address can be changed to one of four options so you can have up to 4 ADS1115’s connect on a single 2-wire I2C bus for 16 single end inputs.
There is an example code for both Raspberry Pi and Arduino. For this purpose connect GND to Ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port and run the example code to start reading data.
