The Analog Devices ADuCM355 is a precision analog microcontroller designed specifically for electrochemical and impedance measurement applications. The device integrates a complete analog front end (AFE) optimized for sensor measurement along with an ARM Cortex-M3 processor, enabling both signal acquisition and embedded processing within a single chip. This level of integration reduces external component count and simplifies system design for portable and compact instrumentation.
At the core of the ADuCM355 is a configurable, high-precision analog subsystem that supports amperometric, voltammetric, and impedance spectroscopy measurements. The device includes integrated DACs, ADCs, transimpedance amplifiers, and waveform generation capabilities, enabling accurate excitation and measurement of electrochemical sensors. This makes it well suited for applications requiring precise current and voltage control and measurement across a range of sensor types.
The microcontroller architecture allows users to process measurement data locally, implement calibration algorithms, and manage communications without the need for an external processor. Its low power design supports battery-operated and portable instrumentation, while integrated peripherals and memory resources enable flexible firmware development. The high level of analog integration reduces board space and helps improve signal integrity by minimizing routing complexity.
Typical applications for the ADuCM355 include gas sensing, chemical analysis, biosensing, and industrial process monitoring where electrochemical measurement techniques are required. The device is engineered to provide accurate, repeatable results in compact systems used in healthcare diagnostics, environmental monitoring, and industrial instrumentation.
