Maxim公司的MAX30001是超低功耗单路生物电位(ECG,R–R和步速检测)和生物阻抗步速检测模拟前端(AFE)解决方案,生物电位和生物阻抗通路具有ESD保护,EMI滤波,内部电极偏压,DC电极断线检测,待机模式电极连线检测,以及用于内置自测的大范围校准电压.生物电位通路提供ECG波形,心率和起搏器边缘检测,而生物阻抗通路能够测量呼吸.主要用在心律失常检测,病人监护无线贴片,生物认证和ECG按需应用,呼吸和水合监测仪以及基于阻抗的心率检测.本文介绍了MAX30001主要优势和特性,功能框图和应用电路,以及评估系统MAX30001 EVK主要特性,应用电路,电路图,材料清单和PCB设计图.

The MAX30001 is a complete, biopotential and bioimpedance (BioZ), analog front-end (AFE) solution for wearable applications. It offers high performance for clinical and fitness applications, with ultra-low power for long battery life. The MAX30001 is a single biopotential channel providing electrocardiogram (ECG) waveforms, heart rate and pacemaker edge detection, and a single bioimpedance channel capable of measuring respiration.

The biopotential and bioimpedance channels have ESD protection, EMI filtering, internal lead biasing, DC leads-off detection, ultra-low-power, leads-on detection during standby mode, and extensive calibration voltages for built-in self-test. Soft power-up sequencing ensures no large transients are injected into the electrodes. Both channels also have high input impedance, low noise, high CMRR, programmable gain, various low-pass and high-pass ..
