Analog Devices, Inc. unveiled a high-precision, low-power meter-on-a-chip for a range of portable health applications such as point-of-care diagnostics, home/self-test health devices, and wearable vital signs monitors, including those for sports and fitness. The ADuCM350 single-chip, scalable platform 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, with a processing subsystem and an industry-standard software development environment to support a complete product development roadmap. The ADuCM350 meter-on-a-chip offers easy connectivity to passive and active sensors and supports sensor fusion functionality that enables exceptionally accurate measurements of human physiological data even in the presence of interferers.

The ADuCM350 is a complete meter-on-a-chip optimized for portable health applications such as point-of-care diagnostics, remote health/vital signs monitoring and home/self-test health meters. 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 key features include: 16-bit accurate 160 kSPS A/D converter; 0.2% precision voltage reference; 12-bit no missing code D/A converter; hardware accelerators for waveform generation and filtering; 16-MHz ARM(R) Cortex(TM) M3 processor; 384-kB flash memory, 16-kB EEPROM and 32-kB SRAM; sensor fusion support; configurable switch matrix (amperometric, photometric, impedance, potentiometric); complex impedance measurement (waveform generation and filtering); robust capacitance-to-digital conversion technology; communication I/O support: USB, audio, display, beeper, and serial; extensive power management capabilities; and Operation: Coin cell battery compatible.

ADuCM350 sample is now available. This product full production will start in April 2014. The product price is $7.50.
