Key features, specifications, target applications
CEM102, a state-of-the-art miniaturized analog front-end (AFE), enables electrochemical sensing with highest accuracy at very low currents. With its small form factor and the industry’s lowest power consumption, it is ideal for applications that rely on battery-operated electrochemical sensors, allowing engineers to create versatile and compact solutions for industrial, environmental and healthcare applications such as air and gas detection, food processing and agricultural monitoring as well as medical wearables such as continuous glucose monitors.
Competitive advantages
The CEM102 is designed to be used together with the RSL15 Bluetooth^® 5.2 enabled microcontroller, which provides the industry’s lowest power Bluetooth Low Energy technology. As a complete electronics solution, it allows biosensors and environmental sensors to accurately measure chemical current while operating with very low system power consumption and wide supply voltage range. The seamless integration of the two components, along with their compact size and industry-leading power efficiency, play a crucial role in making devices smaller and ensuring their long-lasting functionality – a vital factor for battery-powered solutions. The solution offers greater accuracy, noise reduction and low power consumption compared to other offerings. It also allows for a simplified bill of materials (BoM), easy calibration and reduces manufacturing complexity.
With a broad 1.3 to 3.6 V supply voltage range, the system can operate from a 1.5 V silver oxide battery or a 3 V coin cell. Its operation consumes just 50 nA in disabled mode, 2 uA in sensor biased mode, and 3.5 uA in active measurement mode with the 18-bit ADC continuously converting. This translates to a market leading 14 days of operation with only a 3 mAh battery or several years with larger size batteries.
