ADAS1000-2BSTZ

模拟前端 – AFE 5 Electrode ECG AFE

Low Power, Five Electrode  Electrocardiogram (ECG) Analog Front End

GENERAL DESCRIPTION ADAS1000-2BSTZ

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.
