Analog Devices unveils biological- and chemical-sensing interface IC

June 27, 2018

Norwood, MA (BUSINESS WIRE). Analog Devices Inc. announced today 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 company said, the ADuCM355 precision analog microcontroller with biosensor and chemical-sensor interface is suitable for applications such as industrial gas sensing, instrumentation, vital-signs monitoring, and disease management. The device features sensor diagnostics as well as low-noise and low-power performance and a small form factor. Compared with traditional discrete solutions, which pose limitations and require multiple ICs to achieve similar performance, ADI said its new microcontroller platform offers increased reliability, flexibility, and cost savings.

“Analog Devices’ new ADuCM355 uniquely combines the high performance, ultralow 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.”

“PalmSens is committed to make electrochemistry easier, more portable, and more accessible for customers,” said Niels van Velzen, CTO at PalmSens. “ADI’s ADuCM355 is at the heart of the new EmStat Pico, the world’s smallest general-purpose electrochemical interface module. EmStat Pico is a complete hardware and software design platform that allows measurement in minutes and is ideal for the development of portable, wearable and space constrained sensor applications.”

The ADuCM355 is an ultra-low power precision analog microcontroller based on the ARM Cortex M3 processor especially designed to control and measure chemical and biosensors. It is the only solution available that supports dual potentiostat and >3 sensor electrodes. Additional features include

  • voltage, current and impedance measurement;
  • dual ultralow power, low-noise potentiostats (8.5 mA, 1.6 mV RMS);
  • flexible 16-bit, 400-kS/s measurement channel;
  • advanced sensor diagnostics;
  • integrated analog hardware accelerators;
  • 26-MHz core, 128 kB Flash, and 64 kB SRAM.
