Description
The MAX30003 is a complete, biopotential, analog frontend 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 0°C to +70°C commercial temperature range.
