Summary

The Texas Instruments ADC ADS1015 Auto Scan component provides 12-bit analog-to-digital conversion with automatic channel scanning and comparator functionality. It communicates using the I2C interface and supports multiple input channels with individual configuration.

Description

The ADS1015 Auto Scan is a multi-channel version of the precision 12-bit analog-to-digital converter with automatic channel sequencing capability. It features four independently configurable input channels that can be set up for single-ended or differential measurements, with programmable gain, sample rate, and scanning order. The component includes a programmable comparator for threshold detection across all channels, making it ideal for applications requiring continuous monitoring of multiple analog signals with high-speed conversion and minimal microcontroller intervention.
