onsemi has announced the availability of the CEM102, a state-of-the-art miniaturized analog front-end (AFE). Particularly, it enables electrochemical sensing with highest accuracy at very low currents.

With its small form factor and the industry’s lowest power consumption, it allows engineers to create versatile and compact solutions. Specifically, for industrial, environmental, and healthcare applications.

Promotes Safety, Efficiency

From life and environmental sciences to industrial material and food processing, the ability to measure chemicals can provide greater insights. Therefore, elevating safety, efficiency, and awareness.

In laboratories, mining operations, and material manufacturing, electrochemical sensors such as potentiostat or corrosion sensors serve as important tools. This is because they provide feedback within production systems and manage hazardous substances. Thus, ensuring not only the proper functioning of the process but also the safety of employees and operation.

By creating very small and extremely low-power solutions, the CEM102 is ideal for applications that rely on battery-operated electrochemical sensors. Moreover, industrial safety equipment such as portable gas detection will alert workers of potential hazards when they are in remote settings or where mobility is necessary.

The design of CEM102 is to work together with the RSL15 Bluetooth^® 5.2-enabled microcontroller. This 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. On the other hand, it operates with very low system power consumption and a 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. That is, making devices smaller and ensuring their long-lasting functionality – a vital factor for battery-powered solutions.

Other Features, Functions

The combined offering is part of onsemi’s analog and mixed-signal portfolio, designed to streamline development and promote greater integration and innovation for the next generation of amperometric sensor technologies.

Moreover, it provides designers with optimal flexibility for creating high-performance, energy-efficient, and interconnected applications. Aside from that, the solution offers greater accuracy, noise reduction, and low power consumption. Thus, 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. Furthermore, its operation consumes just 50nA in disabled mode, 2uA in sensor-biased mode, and 3.5uA in active measurement mode with the 18-bit ADC continuously converting. Thus, this translates to a market-leading 14 days of operation with only a 3mAh battery or several years with larger size batteries.
