Click here for production status of specific part numbers. MAX30001 Ultra-Low-Power, Single-Channel Integrated Biopotential (ECG, R-to-R, and Pace Detection) and Bioimpedance (BioZ) AFE General Description The MAX30001 is a complete, biopotential and bioimpedance (BioZ), analog front-end (AFE) solution for wearable applications. It offers high performance for clinical and fitness applications, with ultra-low power for long battery life. The MAX30001 is a single biopotential channel providing electrocardiogram (ECG) waveforms, heart rate and pacemaker edge detection, and a single bioimpedance channel capable of measuring respiration. The biopotential and bioimpedance channels have ESD protection, EMI filtering, internal lead biasing, DC leadsoff detection, ultra-low-power, leads-on detection during standby mode, and extensive calibration voltages for builtin 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.
