Ultra-Low Power 12-Bit Dual-Channel SAR Analog-to-Digital Converter with Autonomous Sensor Monitoring

The ADS7142IRUGR is a compact and energy-efficient 12-bit analog-to-digital converter designed for intelligent sensor monitoring in embedded and battery-powered systems. Developed by Texas Instruments, this device features a dual-channel analog multiplexer that feeds a high-performance SAR ADC, enabling efficient measurement of multiple analog signals with minimal system overhead.

The ADC integrates autonomous monitoring features such as programmable digital window comparators, event counters, and threshold-based interrupt generation. These capabilities allow the device to monitor sensor signals independently and alert the host processor only when required, significantly reducing system power consumption. With an ultra-low power consumption of around 900 nW and a compact X2QFN-10 package, the ADS7142 is ideal for space-constrained and battery-operated applications such as wearable electronics, IoT sensors, and portable monitoring devices.
