general description the max30003 is a complete, biopotential, analog front- end solution for wearable applications. it offers high performance for clinical and fitness applications, with ultra-low power for long battery life. the max30003 is a single biopotential channel providing ecg waveforms and heart rate detection. the biopotential channel has 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. the biopotential channel also has 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 electrosurgery. the max30003 is available in a 28-pin tqfn and 30-bump wafer-level package (wlp), operating over the 0c to +70c commercial temperature range. applications single lead event monitors for arrhythmia detection single lead wireless patches for at-home/ in-hospital monitoring chest band heart rate monitors for fitness applications bio authentication and ecg-on-demand applications beneits and features clinical-grade ecg afe with high-resolution data converter ? 15.5 bits effective resolution with 5v p-p noise better dry starts due to much improved real world cmrr and high input impedance ? fully differential input structure with cmrr > 100db offers better common-mode to differential mode conversion due to high input impedance ? high input impedance > 500m for extremely low common-to-differential mode conversion minimum signal attenuation at the input during dry start due to high electrode impedance high dc offset range of 650mv (1.8v, typ) allows to be used with wide variety of electrodes high ac dynamic range of 65mv p-p will help the afe not saturate in the presence of motion/direct electrode hits longer battery life compared to competing solutions ? 85w at 1.1v supply voltage leads-on interrupt feature allows to keep c in deep sleep mode with rtc off until valid lead condition is detected ? lead-on detect current: 0.7a (typ) built-in heart rate detection with interrupt feature eliminates the need to run hr algorithm on the controller ? robust r-r detection in high motion environment at extremely low power conigurable interrupts allows the c wake-up only on every heart beat reducing the overall system power high accuracy allows for more physiological data extractions 32-word fifo allows you to wake up controller every 256ms with full ecg acquisition high-speed spi interface shutdown current of 0.5a (typ) ordering information appears at end of data sheet. 19-8558; rev 0; 6/16 max30003 ultra-low power, single-channel integrated biopotential (ecg, r to r detection) afe abridged data sheet downloaded from: http:///
