During Sensors Expo 2018 in San Jose, CA, Analog Devices announced a new sensor interface IC that enables the next generation of intelligent electrochemical sensors. As the only solution available to incorporate potentiostat and Electrochemical Impedance Spectroscopy (EIS) functionality on a single chip, the ADuCM355 precision analog microcontroller with bio-sensor and chemical sensor interface is a viable solution for applications such as industrial gas sensing, instrumentation, vital signs monitoring and disease management.
The device features the industry’s most advanced sensor diagnostics, best-in-class low noise and low power performance, and smallest form factor. Compared to traditional discrete solutions, which pose limitations and require multiple ICs to achieve similar performance, ADI’s new microcontroller platform offers increased reliability, utmost flexibility and significant cost savings.
The ADuCM355 is an ultra-low power precision analog microcontroller based on the ARM Cortex M3 processor and is designed to control and measure chemical and biosensors. It is said to be the only solution available that supports dual potentiostat and more than three sensor electrodes. Additional features include:
- Voltage, current and impedance measurement
- Dual ultra-low power, low noise potentiostats: 8.5 µA, 1.6 µVRMS
- Flexible 16-bit, 400 ksamples/s measurement channels
- Advanced sensor diagnostics
- Integrated analog hardware accelerators
- 26 MHz core, 128 kB Flash, 64 kB SRAM
