Ads1115 adc converter

Precision 16‑bit I²C ADC With Programmable Gain & Low‑Power Operation

The ADS1115 is a highly integrated, low‑drift 16‑bit analog‑to‑digital converter designed for portable and battery‑powered measurement systems. Featuring a built‑in programmable gain amplifier (PGA) and flexible I²C communication, it converts a wide range of sensor signals with sub‑microvolt accuracy. Its low quiescent current (0.2 µA) and configurable data rates (up to 860 sps) make it ideal for high‑resolution sensing in wearable, industrial, and aerospace applications.

Aluminum package options and robust isolation between the input and I²C bus add electrical safety and noise immunity. The ADS1115’s automatic zero‑drift calibration and selectable input bandwidth allow you to optimize for either ultra‑low noise measurements or fast transient capture.
