ADI ADAS1000系列12导联ECG测量系统设计方案

ADI公司的ADAS1000/ADAS1000-1/ADAS1000-2是低功耗心电图(ECG)模拟前端，实现了12导联心电图(ECG)信号测量,呼吸测量,起搏信号检测和导联脱落检测等功能.支持AAMI EC11:1991/(R)2001/(R)2007,AAMI EC38 R2007,EC13:2002/(R)2007,IEC60601-1 ed.3.0 b:2005,IEC60601-2-25 ed.2.0 :2011,IEC60601-2-27 ed.2.0 b:2005, IEC60601-2-51 ed. 1.0 b: 2005.主要用在ECG监测器和诊断,病人监视器,Holter,手持遥测设备等.本文介绍了ADAS1000主要特性,功能框图,以及12导联ECG测量系统设计方案框图,电路图和PCB元件布局图等.
The ADAS1000/ADAS1000-1/ADAS1000-2 measure electro cardiac (ECG) signals, thoracic impedance, pacing artifacts, and lead-on/lead-off status and output this information in the form of a data frame supplying either lead/vector or electrode data at programmable data rates. Its low power and small size make it suitable for portable, battery-powered applications. The high performance also makes it suitable for higher end diagnostic machines.
The ADAS1000 is a full-featured, 5-channel ECG including respiration and pace detection, while the ADAS1000-1 offers only ECG channels with no respiration or pace features. Similarly, the ADAS1000-2 is a subset of the main device and is configured for gang purposes with only the ECG channels enabled (no respiration, pace, or right leg drive).
The ADAS1000/ADAS1000-1/ADAS1000-2 are designed to simplify the task of acquiring and ensuring quality ECG signals. They provide a low power, small data acquisition system for biopotential applications. Auxiliary features that aid in better quality ECG signal acquisition include multichannel averaged driven lead, selectable reference drive, fast overload recovery, flexible respiration circuitry returning magnitude and phase information, internal pace detection algorithm operating on three leads, and the option of ac or dc lead-off detection. Several digital output options ensure flexibility when monitoring and analyzing signals. Value-added cardiac post processing is executed externally on a DSP, microprocessor, or F...
