The MAX30001G is a complete, biopotential and bioimpedance (BioZ), analog front-end (AFE) solution for wearable applications that is targeted for galvanic skin response (GSR) applications. This GSR channel has been optimized for use in consumer wearable applications where the users wants some indication of stress levels to be detected. The MAX30001G has a single biopotential channel providing electrocardiogram (ECG) waveforms plus a low-power integrated heart rate detection algorithm. The single bioimpedance channel is capable of measuring both respiration and galvanic skin resistance (GSR) and electrodermal activity (EDA).
The biopotential and bioimpedance channels have ESD protection, EMI filtering, internal lead biasing, DC leads-off detection, ultra-low-power, leads-on detection during standby mode, and extensive calibration voltages for built-in self-test. Soft power-up sequencing ensures no large transients are injected into the electrodes. Both channels also have high input impedance, low noise, high CMRR, programmable gain, various low-pass and high-pass filter options, and a high-resolution analog-to-digital converter. The biopotential channel is DC coupled, can handle large electrode voltage offsets and has a fast recovery mode to quickly recover from overdrive conditions, such as defibrillation and electro-surgery. The bioimpedance channel includes integrated programmable current drive, works with common electrodes, and has the flexibility for 2 or 4 electrode measurements. The bioimpedance channel also has AC lead-off detection.
The MAX30001 is available in a 30-bump wafer-level package (WLP), operating over the 0°C to +70°C commercial temperature range.
Applications
- Both Continuos and On-Demand ECG Applications
- Stress Monitoring Using GSR/EDA Techniques
