Summary

The Texas Instruments ADS1114 ADC component provides 16-bit analog-to-digital conversion with comparator functionality. It communicates using the I2C interface and converts analog signals to digital values with programmable threshold detection.

Description

The ADS1114 is a precision, low-power, 16-bit analog-to-digital converter with an I2C interface and built-in comparator. It offers high-resolution conversion with programmable gain, sample rate, and comparator settings. The converter features excellent accuracy and includes a programmable comparator for threshold detection, making it suitable for applications requiring precise analog measurements with alert functionality.
