Patrick O'Doherty, vice president of ADI's healthcare department said: "The meter supports a variety of portable medical applications ADuCM350 piece, from smart watches and advanced pedometer such as wearable health monitoring devices, can shorten the hospital stay of patients Nursing point diagnostics, while enabling high-quality home monitoring, the ADuCM350 offers unmatched precision and on-chip integration, making it ideal for use in portable health and healthcare monitoring products."

ADuCM350 on-chip meter for system-level performance optimization

The ADuCM350 is optimized for system-level performance and high-precision signal measurement (including those with a single-button battery-powered monitoring device) and integrates a 16-bit precision 160 kSPS ADC, a +/-0.2% precision reference, and a 12-bit DAC A precision AFE consisting of.

The passive complex impedance sensing capability provided by the ADuCM350 enables baseline detection and provides detailed information on physiological, biological, and electrochemical reactions at previously unachievable performance levels. Passive and active sensor fusion provides additional levels of signal measurement accuracy, while environmentally adaptable on-chip capacitive digital conversion technology supports new applications such as skin electrode detection and next-generation electrochemical stripping technology. Precision AFE performs auto-calibration to ensure accurate, repeatable field measurement over the life of the product.

Scalable development platform supports fast feature expansion

The ADuCM350 Healthcare On-Chip Meter is a flexible application platform that supports a complete product development roadmap from entry-level devices to multi-function devices. Sensor fusion allows designers to extend product measurement capabilities. For example, the ADuCM350 platform uses ultra-low-power 3-axis MEMS accelerometers for height and motion detection, combined with heart rate and respiratory response, to support calorie consumption measurement applications. Rich communication I/O peripherals include USB, audio, display, serial and touch devices to support differentiation and fast function expansion. The ADuCM350 AFE Sequencer allows designers to reliably use the measurement sequence for the entire product line with a single software development for the measurement sequence.
