Product Description
The ADS1115 16-Bit ADC delivers analog to digital conversion for precision measurement applications. This high-performance breakout board features Texas Instruments’ industry-standard ADS1115 chip, providing 16-bit resolution at up to 860 samples per second with built-in programmable gain amplifier (PGA) for optimal signal conditioning. Perfect for Arduino, Raspberry Pi, and microcontroller projects requiring accurate analog signal measurement beyond standard 10-bit ADC capabilities.
With its wide 2V-5.5V supply range and I2C interface, the ADS1115 offers versatility for various measurement scenarios. The programmable gain amplifier provides selectable gains from ±6.144V down to ±0.256V full-scale range, enabling precise measurement of both large and small signals. Four single-ended channels can be configured as two differential pairs, while the built-in voltage reference ensures measurement stability. The easyC connector system simplifies integration, eliminating wiring errors and enabling rapid prototyping for sensor networks, data acquisition systems, and precision measurement applications.
Applicable for sensor networks, building data acquisition systems, or upgrading Arduino projects with analog measurement capabilities, the ADS1115 provides the accuracy and reliability. With comprehensive documentation and professional EU manufacturing quality, this ADC module delivers precision in a maker-friendly package. With our extensive Arduino library, you can get started quickly, without soldering, using our Qwiic (easyC) connector.
