ADS1015 12-Bit ADC - 4 Channel with Programmable Gain Amplifier

by Adafruit

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. We 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 we 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.

This 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.

Fast and efficient delivery as always, jumper wires are short so excellent for project work.

Reasonable quality - great value. The connectors are a little jiggly but secure when pushed in properly.

Another superb purchase from the fabulous team at Pimoroni. Works well for my latest project where I have to construct a connection interface to the Raspberry pi

Nicely coloured to help identify cable runs without ferrules. Bought to assemble a keyboard without soldering to the headers and work a treat. Fits regular length headers, and I would guess long headers as well, with some open contact.

I couldn’t be more pleased with my female to female cables, in life, 2 of is always better than just one.

Great when you need a male to female wire, could possibly de-gender the wires to ensure the LGBTQ+ community are kept pleased, but they are absolutely perfect.

They are short, male to male wires. They’re great. Also very much in tune with the LGBTQ+ community

I am currently employing a breakout garden on my Pi and needed cables to extend the power cords for my fan. This worked perfectly.

These are useful if wanting to solder extended cables or individual things to a GPIO header. They work great.

Super handy and only a few quid so great if you're just grabbing a few bits to start tinkering!

I needed these for my prototyping I would defiantly buy this over and over again amazing product.

Very quick delivery from Pimoroni, as usual - thanks. Like these shorter jumper wires when prototyping small compact projects.

I can use this item to connect Arduino Leonardo ICSP headers to TFT display headers. It is easy to use and I like to choose colours.

A pretty standard set of jumpers, that work as advertised. The different colors help you keep track at what goes where. I find 100mm to be the perfect length for prototyping as well.
