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

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 per second over I2C.

The chip can be configured as 4 single-ended input channels or two differential channels. It includes a programmable gain amplifier (PGA) up to x16 to boost smaller single/differential signals to the full range. The ADC runs on 2V to 5V power/logic, measures a large range of signals, and is very easy to use, making it a great general-purpose 12-bit converter.

This breakout board includes ferrites to keep AVDD and AGND quiet and uses I2C for interfacing. The I2C address can be changed to one of four options, which allows up to 4 ADS1015 devices on a single 2-wire I2C bus, providing 16 single-ended inputs.

It comes with 0.1" standard header for breadboard or perfboard use and features four mounting holes.

Adafruit's custom PCB in the STEMMA QT form factor makes it easy to interface with other compatible devices using solderless connections.
