Overview

This module is ideal for microcontrollers that have no built-in analog-digital converter, or when you need a higher-precision ADC. It provides 12-bit precision at 3300 samples / second over I2C. It can be configured as 4 single-ended input channels, or two differential channels. The module can operate between 2V and 5V, can measure a wide range of signals and is very easy to use. 

The chip is small and comes with ferrites to reduce noise. Communication is via I2C interface. The address can be configured to one of four options so you can connect up to 4 ADS1015 modules to a single I2C bus.

Specifications

• Power supply: 2 V to 5 V
• Low current consumption: 150 μA
• Rate Software: 8 SPS to 860 SPS
• Internal oscillator
• Internal PGA
• 7-bit I2C interface between 0x48 and 0x4B address selectable by jumpers

To start, we have sample code for both the Raspberry Pi ( Adafruit Pi Python library ) and for Arduino ( ADS1015 Arduino library ). Just plug the ground to GND, VDD to power supply and the SCL / SDA to I2C ports of the microprocessor and run code from example.
