MAX30003：Ultra-Low Power, Single-Channel Integrated Biopotential (ECG, R to R Detection) AFE

Ultra-Low Power, Single Channel Integrated Biopotential (ECG) AFE with HR Detection Algorithm (R-R)

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 0°C to +70°C commercial temperature range.

Key Features

Clinical-Grade ECG AFE with High-Resolution Data Converter
- 15.5 Bits Effective Resolution with 5µVP-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 > 500MΩ 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 65mVP-P Will Help the AFE Not Saturate in the Presence of Motion/Direct Electrode Hits
