At the CES 2014, Analog Devices announced the launch of a new chip for portable health applications point-of-care diagnostics, home/self-test health devices, and wearable vital signs monitors, including those for sports and fitness.
Analog Devices said the ADuCM350 single-chip, a low-power meter-on-a-chip, combines a 16-bit accurate analog front-end (AFE), which includes a configurable multi-sensor switch matrix, hardware waveform generator and discrete Fourier transform (DFT) engine.
The ADuCM350 meter-on-a-chip supports portable healthcare applications like wearable health monitoring devices, such as smart watches and sophisticated pedometers and point-of-care diagnostics that shorten hospital stays and make possible high quality monitoring in the home.
The ADuCM350 is optimized for system-level performance and signal measurement accuracy, including those monitoring devices powered by a single coin-cell battery, and features a precision AFE with a 16-bit accurate, 160-kSPS A/D converter, +/-0.2% accurate voltage reference, and a 12-bit D/A converter.
ADuCM350 healthcare meter-on-a-chip supports full product development roadmaps from entry-level to feature-rich devices. Sensor fusion functionality allows designers to expand product measurement capabilities.
For example, the ADuCM350 platform can support calorie burn applications by combining galvanic skin response for heart rate and respiration, with an ultra-low-power 3-axis MEMS accelerometer for altitude and motion detection.
In addition, an extensive peripheral set of communication I/O including USB, audio, display, serial and touch supports differentiation and rapid feature expansion. The ADuCM350 AFE sequencer enables designers to develop the software for a measurement procedure only once and then reliably port it across an entire product family.
