Most advanced biological and chemical sensing Interface IC

Analog Devices has introduced a sensor interface IC that will enable the next generation of intelligent electrochemical sensors.

The device incorporates potentiostat and Electrochemical Impedance Spectroscopy (EIS) functionality on a single chip, the ADuCM355 precision analogue microcontroller with bio-sensor and chemical sensor interface is intended for applications such as industrial gas sensing, instrumentation, vital signs monitoring and disease management.

According to ADI, it features the industry’s most advanced sensor diagnostics, best-in-class low noise and low power performance, and smallest form factor.

The ADuCM355 is based on the ARM Cortex M3 processor. Additional features include: voltage, current and impedance measurement; dual ultra-low power, low noise potentiostats: 8.5uA, 1.6uV RMS; a flexible 16-bit, 400ksps measurement channel; advanced sensor diagnostics; integrated analogue hardware accelerators and 26 MHz core, 128kB Flash, 64kB SRAM.
