## Description

Add precision analog-to-digital conversion to any microcontroller with the ADS1115 breakout. This 16-bit ADC delivers 860 samples per second over I2C, with four single-ended or two differential input channels and a built-in programmable gain amplifier (up to 16×) for boosting small signals. The board runs on 2V to 5V power and logic, and includes ferrites for clean analog supply lines. Up to four ADS1115 boards can share a single I2C bus for 16 single-ended inputs. For faster sampling at lower resolution, consider the ADS1015 12-Bit ADC (3,300 samples/second). Key Features 16-Bit Resolution – High-precision measurements at 860 samples per second 4 Channels – Configurable as 4 single-ended or 2 differential inputs Programmable Gain Amplifier – Up to 16× gain for small signal measurement 2V to 5V Operation – Compatible with both 3.3V and 5V logic I2C Interface – Simple two-wire connection with configurable address Configurable I2C Address – Up to 4 boards on a single bus (16 inputs total) Clean Analog Supply – Onboard ferrites for quiet AVDD and AGND Ideal For Precision sensor measurement and data acquisition Adding analog inputs to digital-only microcontrollers Voltage and current monitoring Multi-channel analog measurement systems Package Contents 1× ADS1115 16-Bit ADC Breakout Board (assembled and tested) 1× Header strip Resources Adafruit Learn Guide (Arduino, Raspberry Pi & CircuitPython) ADS1X15 Arduino Library (GitHub) Adafruit Pi Python Library (GitHub)
