ST HM301D和STM32诊断级生物电采集系统STEVAL－IME002Vx
ST公司的HM301D是具有三个差分通路的高度集成诊断级生物电采集系统,多个主/从配置支持多达16路同时取样(12路生物电位采集和4路生物阻抗),全集成高通滤波器,每路具有高分辨率和低噪音,输入参考噪音6 μVPP (300 Hz BW,G=64),生物电信号转换高达10kHz,最大数据速率125kSPS,工作电压1.62V-3.6V.主要用在心电图(ECG),病床监视,Holter,临床环境图,自动体外除颤器(AED),脑电图(EEG),肌电图(EMG),可穿戴遥控监视.医疗设备等.本文介绍了HM301D主要特性,框图,标准12线ECG链连接图以及基于HM301D和STM32的评估板STEVAL- IME002Vx主要特性,框图,电路图,材料清单和PCB元件布局图.
The HM301D is a highly integrated diagnostic-quality biopotential acquisition system with 3differential channels. Multi master/slave configuration supports up to 16 channels of simultaneous sampling (12 biopotential acquisitions and 4 bio-impedance channels). A fullyintegrated high-pass filter removes the half-cell DC value to enable the channels to workwith the AC component only. Each channel provides high resolution and low noise conversion of biopotential signals up to 10 kHz.
The input connection circuit matrix guarantees maximum flexibility in terms of electrode cables and connectors.
