Ultra-Low Power, Single-Channel Integrated MAX30003 Biopotential (ECG, R-to-R Detection) AFE General Description Benefits and Features The MAX30003 is a complete, biopotential, analog front- Clinical-Grade ECG AFE with High-Resolution Data end solution for wearable applications. It offers high Converter performance for clinical and fitness applications, with 15.5 Bits Effective Resolution with 5V Noise P-P ultra-low power for long battery life. The MAX30003 is a Better Dry Starts Due to Much Improved Real World single biopotential channel providing ECG waveforms and CMRR and High Input Impedance heart rate detection. Fully Differential Input Structure with CMRR > 100dB The biopotential channel has ESD protection, EMI filtering, Offers Better Common-Mode to Differential Mode internal lead biasing, DC leads-off detection, ultra-low Conversion Due to High Input Impedance power leads-on detection during standby mode, and extensive High Input Impedance > 500M for Extremely Low calibration voltages for built-in self-test. Soft power-up Common-to-Differential Mode Conversion sequencing ensures no large transients are injected into Minimum Signal Attenuation at the Input During Dry the electrodes. The biopotential channel also has high Start Due to High Electrode Impedance input impedance, low noise, high CMRR, programmable High DC Offset Range of 650mV (1.8V, typ) Allows gain, various low-pass and high-pass filter options, and to Be Used with Wide Variety of Electrodes a high resolution analog-to-digital converter. The biopotential channel is DC coupled, can handle large High AC Dynamic Range of 65mV Will Help the P-P electrode voltage offsets, and has a fast recovery mode AFE Not Saturate in the Presence of Motion/Direct to quickly recover from overdrive conditions, such as Electrode Hits defibrillation and electrosurgery. Longer Battery Life Compared to Competing Solutions The MAX30003 is available in a 28-pin TQFN and 85W at 1.1V Supply Voltage 30-bump wafer-level package (WLP), operating over the Leads-On Interrupt Feature Allows to Keep C in 0C to +70C commercial temperature range. Deep Sleep Mode with RTC Off Until Valid Lead Condition is Detected Applications Lead-On Detect Current: 0.7A (typ) Single-Lead Event Monitors for Arrhythmia Detection Built-In Heart Rate Detection with Interrupt Feature Single-Lead Wireless Patches for At-Home/ Eliminates the Need to Run HR Algorithm on the In-Hospital Monitoring Controller Chest Band Heart Rate Monitors for Fitness Applications Robust R-R Detection in High Motion Environment Bio Authentication and ECG-On-Demand Applications at Extremely Low Power Configurable Interrupts Allows the C Wake-Up Only on Ordering Information appears at end of data sheet. 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) 19-8558 Rev 3 9/21 2021 Analog Devices, Inc.
