The ADS1115 is a precision 16-bit analog-to-digital converter (ADC) with a programmable gain amplifier (PGA) and 4 input channels. It can operate as 4 single-ended or 2 differential channels, making it highly versatile for analog signal measurement. With a small form factor and I2C interface, it is easy to integrate with microcontrollers, including Arduino, Raspberry Pi, and ESP32, enabling seamless communication.

This ADC supports a programmable data rate of up to 860 samples per second (SPS) and features a wide operating voltage range from  3.0 to 5.5V, making it suitable for low-power and battery-operated applications. The built-in PGA amplifies weak signals, with configurable gains to accommodate various input voltage levels, improving measurement precision.

The ADS1115’s low power consumption and high resolution make it perfect for applications such as sensor interfacing, signal monitoring, industrial automation, and IoT systems. Its addressable I2C interface allows multiple ADS1115 modules to connect on the same bus.

Compact, efficient, and accurate, the ADS1115 ADC module is ideal for projects requiring high-resolution analog-to-digital conversion, delivering reliable and consistent performance across a variety of environments.
