ADS1115 16-Bit I2C ADC 4-Channel Programmable Gain Amplifier Module

The ADS1115 is a 16-bit ADC with 4 channels and a programmable gain amplifier. It's ideal for microcontrollers lacking an analog-to-digital converter or when higher precision is required. Offering 16-bit resolution at 860 samples per second via I2C, this chip can be set up for either 4 single-ended input channels or 2 differential channels. It also features a programmable gain amplifier with up to x16 amplification to enhance smaller signals.

We appreciate this ADC for its versatility, operating from 2V to 5V power/logic, and its ease of use. The chip is compact and mounted on a breakout board with ferrites to minimize noise on AVDD and AGND. It interfaces through I2C, and its address can be set to one of four options, allowing up to 4 ADS1115 chips on a single 2-wire I2C bus for up to 16 single-ended inputs.

For quick setup, we offer example code for both Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository). Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller’s I2C port, then run the example code to begin reading data.
