A new sensor interface IC has been announced by Analog Devices, Inc. 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.
“Analog Devices’ new ADuCM355 uniquely combines the high performance, ultra-low power, small form factor and advanced feature set needed to enable next generation portable gas detectors,” said Jacob Spector, global marketing manager, Portable Gas Detection for Honeywell Industrial Safety. “We are excited about the ability to leverage this platform solution to set new benchmarks in reliable gas detection while minimizing the cost of ownership for our customers”, he added.
