Analog Devices Inc. ADAS1000-2BSTZ

Description
The ADAS1000/ADAS1000-1/ADAS1000-2 are low-power, five-electrode electrocardiogram (ECG) analog front ends. They measure electrocardiac (ECG) signals, thoracic impedance, pacing artifacts, and lead-on/lead-off status. The output is a data frame supplying either lead/vector or electrode data at programmable data rates.
The ADAS1000 is a full-featured, 5-channel ECG including respiration and pace detection. The ADAS1000-1 offers only ECG channels with no respiration or pace features. 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).
