January 8, 2014 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, today unveiled a high-precision, low-power meter-on-chip for use in a variety of portable medical applications, including point-of-care diagnostics, home/self-diagnostic medical devices, and wearable biosignal monitors for sports and fitness monitoring. The ADuCM350 single-chip, a scalable platform, supports a complete product development roadmap by integrating a 16-bit precision analog front-end (AFE) containing a configurable multi-sensor switch matrix, a hardware waveform generator, and a discrete Fourier transform (DFT) engine into a processing subsystem and an industry-standard software development environment. The ADuCM350 meter-on-chip can be easily connected to passive and active sensors and enables very precise measurement of human physiological data even in the presence of interference.
Patrick O'Doherty, Vice President of Healthcare at Analog Devices, emphasized, “The ADuCM350 meter-on-chip can be applied to a wide range of portable medical applications, from wearable healthcare monitoring devices such as smartwatches and sophisticated pedometers to point-of-care diagnostic devices that provide excellent monitoring performance at home and can reduce hospital stays,” adding, “With its exceptional accuracy and high on-chip integration, the ADuCM350 is perfectly suited for designing portable devices for health monitoring.”

ADuCM350 meter-on-chip optimized for system-level performance
The ADuCM350 is optimized for system-level performance and precision of signal measurements, including monitoring equipment that operates on a single coin-cell battery, and features an AFE with 16-bit accuracy, a 160-kSPS A/D converter, a voltage reference with ±0.2% accuracy, and a 12-bit D/A converter.
The passive complex impedance sensing capability of the ADuCM350 enables the detection of previously unknown thresholds and detailed information on physiological, biological, and electrochemical reactions. The fusion of passive and active sensors has further enhanced signal measurement accuracy, and thanks to environmentally robust on-chip capacitance-to-digital technology, it can be applied to new fields such as skin electrode detection and next-generation electrochemical test strip technology. The precision AFE ensures accurate and repeatable measurements throughout the product's lifespan through automatic calibration.

A scalable development platform that enables the easy and rapid addition of new features
The ADuCM350 healthcare meter-on-chip is a flexible platform that supports the entire product development roadmap, from basic specifications to multi-functional devices. Sensor fusion capabilities enable designers to easily extend the system's measurement functions. For example, the ADuCM350 platform combines galvanic skin response for heart rate and respiration with an ultra-low-power 3-axis MEMS accelerometer for motion detection, making it useful for developing calorie-burning applications. An extensive set of communication I/O peripherals, including USB, audio, display, serial, and touch, allows for product differentiation and rapid functional expansion. Additionally, using the ADuCM350 AFE sequencer, developers can create measurement procedures platform-independently at the developer stage and extend them to the entire product family as needed.
