Summary

The Texas Instruments ADS1115 ADC component provides high-precision 16-bit analog-to-digital conversion with programmable gain and multiple input configurations. It communicates using the I2C interface and offers advanced features including a programmable comparator.

Description

The ADS1115 is a precision, low-power, 16-bit analog-to-digital converter with an I2C interface. It features a programmable gain amplifier (PGA), multiple input channels configurable as single-ended or differential inputs, and a built-in comparator with programmable threshold detection. The converter offers excellent accuracy and noise performance, making it suitable for a wide range of precision measurement applications including sensor monitoring, data acquisition systems, and industrial instrumentation.
