At Analog Devices, we make technologies that sense, measure, interpret, and connect—bridging the physicaland digital worlds to form the foundation of the Internet of Things. Our technologies are designed to maximize
system-level intelligence and reliability, enabling applications where the quality and integrity of data and insights
are mission critical. The brain of the connected solution—processors—combines hardware and advanced
algorithms to interpret data to deliver intelligence, functionality, and localized decision making for IoT solutions. The ADuCM4050 offers class leading, ultra
low power active and hibernate modes for IoT applications where power consumption, security, and robustness are key requirements. System power
can be optimized with digital sensors and ultra low power transceivers using SensorStrobe™ technology in the ADuCM4050.
