Description:
The ADS1115 16-Bit ADC 4-Channel Module with Programmable Gain Amplifier is a high-precision analog-to-digital converter designed for Arduino, Raspberry Pi, ESP32, and other microcontroller-based projects that require accurate analog signal measurement. It delivers ultra-precise 16-bit resolution with a sampling rate of up to 860 samples per second through the I2C communication interface, making it ideal for sensor monitoring, automation systems, robotics, and data acquisition applications.
This versatile ADC module can be configured as four single-ended input channels or two differential input channels, allowing flexible signal measurement options for a wide range of electronics projects. The built-in programmable gain amplifier (PGA) supports gains up to x16, enabling the module to amplify very small analog signals and improve measurement accuracy for low-voltage sensors and sensitive devices.
Operating within a wide voltage range of 2V to 5V, the ADS1115 module is compatible with both 3.3V and 5V systems. Its low-noise breakout board design includes ferrite filtering for stable analog performance and cleaner signal readings. Communication is handled through the I2C interface, and the module supports four selectable I2C addresses, allowing multiple ADS1115 modules to be connected on the same bus for expanded analog input capability up to 16 single-ended channels.
