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 an ideal 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.
