For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. Adafruit like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and it's super easy to use. It is a great general purpose 12 bit converter.

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs.

Comes with a bit of 0.1" standard header in case you want to use it with a breadboard or perfboard.  Four mounting holes for easy attachment. 

To get you going fast, Adafruit spun up a custom-made PCB in the STEMMA QT form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the ADS1015 or to chain it with a wide range of other sensors and accessories using a compatible cable.

QT Cable is not included, but Adafruit have a variety in the shop.

Adafruit have example code for both the Raspberry Pi, Arduino and CircuitPython. Simply 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.

Adafruit's detailed guide will get you started with wiring diagrams, example code for Arduino & CircuitPython, datasheets, and more!

Technical Details

Revision History:

  • As of November 21, 2022 – Adafruit have updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen. Additionally, this sensor breakout may come with black or tan STEMMA QT connectors. They work the same!
  • As of June 22, 2022 - Adafruit have updated this breakout to be STEMMA QT compatible - that means there's now an easy way to plug-and-play this device without any soldering! The physical shape and pinout have changed a little but overall functionality is identical.

Specifications:

  • WIDE SUPPLY RANGE: 2.0V to 5.5V
  • LOW CURRENT CONSUMPTION: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • PROGRAMMABLE DATA RATE: 128SPS to 3.3kSPS
  • INTERNAL LOW-DRIFT VOLTAGE REFERENCE
  • INTERNAL OSCILLATOR
  • INTERNAL PGA
  • I2C INTERFACE: Pin-Selectable Addresses
  • FOUR SINGLE-ENDED OR TWO DIFFERENTIAL INPUTS
  • PROGRAMMABLE COMPARATOR
  • This board/chip uses I2C 7-bit addresses between 0x48-0x4B, selectable with jumpers
