12-Bit 8-Channel SAR Analog-to-Digital Converter with Autonomous Sensor Monitoring and I2C Interface

The ADS7128IRTER is a highly integrated 12-bit analog-to-digital converter designed for efficient multi-channel sensor monitoring and low-power data acquisition systems. Developed by Texas Instruments, this SAR ADC includes an 8-channel analog multiplexer that allows multiple sensors or analog signals to be measured using a single device, making it ideal for compact embedded designs.

This device features autonomous monitoring capabilities that help reduce processor workload by enabling event-driven measurements. It includes programmable digital window comparators with threshold detection, hysteresis, and event counting for intelligent signal monitoring. The ADS7128 communicates through a high-speed I2C interface and integrates an internal oscillator and data buffer, simplifying system design while maintaining high measurement accuracy. Its compact WQFN-16 package and ultra-low power operation make it suitable for portable electronics, industrial monitoring, and IoT applications.
