Datasheet

Designed for a variety of portable health applications including point-of-care diagnostics, home/self-test health devices, and wearable vital signs monitors (for health and sports applications), the ADuCM350 has been announced by Analog Devices. Offering high precision and low power consumption, this single-chip solution is comprised of a 16-bit accurate AFE, processing subsystem and an industry-standard software development environment.

Optimised for system-level performance and signal measurement accuracy (including those monitoring devices powered by a single coin-cell battery) the ADuCM350 offers easy connectivity to passive and active sensors and supports sensor fusion functionality that enables exceptionally accurate measurements of human physiological data (even when interference is present). This sensor fusion functionality enables designers to expand product measurement capabilities: the ADuCM350 supports 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.

The integrated AFE (which includes a configurable multi-sensor switch matrix, hardware waveform generator and discrete Fourier transform engine) features a 16-bit accurate, 160-kSPS ADC, +/-0.2% accurate voltage reference, and a 12-bit DAC. Differentiation and expansion is possible through the extensive communication I/O, which include USB, audio, display, serial and touch peripherals.

Patrick O’Doherty, Vice President, Healthcare Group, Analog Devices, commented: "The ADuCM350 meter-on-a-chip supports a wide range of portable healthcare applications ranging from wearable health monitoring devices, such as smart watches and sophisticated pedometers, to point-of-care diagnostics that shorten hospital stays and make possible high quality monitoring in the home. The ADuCM350 offers exceptional accuracy and integration on-chip making it ideally suited for designing portable products that monitor health and wellness."

Sampling now with full production scheduled for April 2014, the ADuCM350 is supplied in a 120-pin 8x8mm CSP_BGA package. It is priced at $7.50 (USD) each in 1,000 unit quantities.
