Overview
The ADAS1000-2BSTZ, produced by Analog Devices Inc., is a low-power, 5-electrode Electrocardiogram (ECG) Analog Front End (AFE) companion chip. It is designed to measure electrocardiac (ECG) signals and lead-on/off status, and is part of the ADAS1000 family of ECG front ends. This device is optimized for gang mode operation, with only the ECG channels enabled, making it suitable for applications requiring high-quality ECG signal acquisition without respiration, pace, or right leg drive features.
