MAX30001 Ultra-Low-Power, Single-Channel Integrated Biopotential (ECG, R-to-R, and Pace Detection) and Bioimpedance (BioZ) AFE General Description Benefits and Features The MAX30001 is a complete, biopotential and bioimpedance Can be Used in IEC 60601-2-47:2012 Compliant (BioZ), analog front-end (AFE) solution for wearable Systems applications. It offers high performance for clinical Clinical-Grade ECG and BioZ AFE with High and fitness applications, with ultra-low power for long Resolution Data Converter battery life. The MAX30001 is a single biopotential 15.9 Bits ENOB with 3.1V (typ) Noise for ECG P-P channel providing electrocardiogram (ECG) waveforms, 17 Bits ENOB with 1.1V Noise for BioZ P-P heart rate and pacemaker edge detection, and a single Better Dry Starts Due to Much Improved Real World bioimpedance channel capable of measuring respiration. CMRR and High Input Impedance The biopotential and bioimpedance channels have ESD Fully Differential Input Structure with CMRR > 100dB protection, EMI filtering, internal lead biasing, DC leads- Offers Better Common-Mode to Differential Mode off detection, ultra-low-power, leads-on detection during Conversion Due to High Input Impedance standby mode, and extensive calibration voltages for built- High Input Impedance > 1G for Extremely Low in self-test. Soft power-up sequencing ensures no large Common-to-Differential Mode transients are injected into the electrodes. Both channels also have high input impedance, low noise, high CMRR, Minimum Signal Attenuation at the Input During Dry programmable gain, various low-pass and high-pass filter Start Due to High Electrode Impedance options, and a high resolution analog-to-digital converter. High DC Offset Range of 650mV (1.8V, typ) Allows The biopotential channel is DC coupled, can handle large to Be Used with Wide Variety of Electrodes electrode voltage offsets, and has a fast recovery mode High AC Dynamic Range of 65mV for ECG and P-P to quickly recover from overdrive conditions, such as defi- 90mV for BioZ Will Help Prevent Saturation in the P-P brillation and electro-surgery. The bioimpedance channel Presence of Motion/Direct Electrode Hits includes integrated programmable current drive, works Longer Battery Life Compared to Competing Solutions with common electrodes, and has the flexibility for 2 or 85W at 1.1V Supply Voltage for ECG 4 electrode measurements. The bioimpedance channel 158W at 1.1V Supply Voltage for BioZ also has AC lead off detection. Leads-On Interrupt Feature Allows to Keep the C The MAX30001 is available in a 30-bump wafer-level in Deep Sleep Mode Until Valid Lead Condition is package (WLP), operating over the 0C to +70C com- Detected mercial temperature range.
