It consumes low-power and enables synchronised measurement of electrocardiogram (ECG), heart rate, SpO2 and respiration rate
Medical device designers aim to facilitate less expensive healthcare-related expenditures by replacing large monitoring systems with smaller, lower power, wireless devices that can be worn discreetly and continuously in the home or office. Now, this can be achieved using the new MAX86178 analogue front-end (AFE) from Analog Devices, Inc, which is suitable for designing wearable remote patient monitoring (RPM) devices. By integrating three measurement systems (optical, ECG and bio-impedance), the single-chip obtains four common vital signs: electrocardiogram (ECG or EKG), heart rate (ECG or optical PPG), blood-oxygen saturation (SpO2) and respiration rate (using BioZ). The MAX86178 enables synchronised optical PPG and ECG timing for derived health metrics.
由于下一代可穿戴的RPM需要低功率来适应较小的电池或延长电池寿命以满足各种充电要求，因此MAX86178可为每个子系统提供具有可配置选项的超低功率，以优化特定用例的电池寿命。
“通过将三个医疗保健子系统集成到一件硅上，模拟设备在其DNA上构建并提供了这种传感器融合产品，” Maxim Integrated的工业和医疗保健业务部门执行业务经理Andrew Burt说，现在是Analog设备的一部分。。“此AFE引起了医学界的共鸣，因为它为慢性病管理，传染性疾病诊断和远程监测带来了新的可能性。MAX86178可以通过使人们离开医院来改善医疗保健的小型设备，从而改善医疗保健的交付并降低成本。”
此外，Analog设备还提供了MAX20343 BUCK-BOOST调节器和Max20360电源管理IC作为针对2.6mm x 2.8mm包装MAX86178和MAX86178EVKIT＃优化的电源解决方案。
